\"So full, so full.\" The doctor said, patting his round belly.

Not long after the time when Xiaobai and the doctor played games together, Xiaobai remembered that it was almost lunchtime, so he said to the doctor and went into the kitchen, looked at the rice cooker that had tripped, and it didn't take long to fry the dishes and serve them to the table.

And above, the doctor is satisfied with the Chinese food.

"I don't know how long it's been since I've had lunch at home.\" The doctor said nostalgically.

"Doctor, sit down and rest, I'll clean up the table first.\" Xiaobai smiled as he said as he cleaned up the plates and bowls that had been eaten.

\"I'm here to help.\" The doctor stood up and joined in the aftermath.

\"...\" Xiaobai smiled and didn't stop the doctor's help, and it was good to exercise after eating.

...

"Xiaobai, do you listen to music?" asked the doctor as he wiped the dishes that Xiaobai handed over with a rag.

\"Well, I like it, especially the Beatles.\" Xiaobai washed the dishes as he handed the washed tray to the doctor next to him.

\"Really??\Does Xiaobai like the Beatles too?\" The doctor stopped what he was doing and looked at Xiaobai in surprise.

\"Hmm.\" Xiaobai nodded lightly and put the washed dishes beside him.

\"I didn't expect you to like the Beatles.\" The doctor laughed as he wiped the disc.

\"Well, is there a problem?\" Xiaobai asked.

\"I thought the Beatles were only for an old man like me, but I didn't expect you to like it too, why don't we hear it later?\" The doctor put the cleaned plate aside, then took the freshly washed plate and wiped it off.

\"Well, that's not bad either.\" Xiaobai smiled.

...

\"The Doctor really likes the Beatles.\" Xiaobai watched the Doctor run to his bedroom, and then took out a CD not long after, which was exactly the Beatles that the Doctor liked.

\"Xiaobai, you wait, I'll put it on to you right away.\" The doctor said excitedly, ran to the TV, turned on the power, turned on the TV and DVD, and put the CD in.

\"Doctor, have you read all these books?\" Xiaobai walked to the TV, looked at the long bookshelf behind the TV and asked.

"Well, yes, I liked to read books when I was younger, but I can't compare to Shinichi's house, whose bookshelf is much bigger than mine.\" The doctor replied as he picked up the song with the remote control.

"Huh?\" Xiaobai took out a few stacks of envelopes from behind the TV.

\"Doctor, these...\" Xiaobai looked at the envelope in his hand and looked at the doctor suspiciously.

\"New Year's cards, summer greetings, and driver's license renewal notice.\" Xiaobai glanced at it and gave it all to the doctor.

"Oh (wo)... I thought I had lost it.\" The doctor walked over to the coffee table as he flipped through the envelope handed over by Xiaobai.

After sitting on the couch, the doctor suddenly fell silent, and looked at a postcard in his hand with a hint of a smile, as if he had thought of something.

In the hall, the music of the Beatles was playing, and with the sound of rock melodies, the Doctor's eyes were reflected in his glasses because of his head lowered, so that he could not see his gaze, and if he was closer, he might be able to see what his eyes were missing.

\"It seems that the doctor has not forgotten.\" Xiaobai looked at the doctor who was caught in the memory, and thought silently in his heart.

"Doctor, what's wrong?\" Xiaobai's voice reached the doctor's ears along with the Beatles' music, and because of this, the doctor woke up from his memories.

\"Oh.\" The doctor was stunned for a moment and looked at Xiaobai.

\"Doctor, what happened just now?\" Xiaobai asked as he looked at the doctor who had woken up from his nostalgia.

\"It's because of this postcard.\" The doctor gave the postcard to Xiaobai.

\"Thank you very much for these 3 months, it's a very happy thing to know Asasa, I don't like to say goodbye, so we have to meet again, 10 years later, the sun father-in-law Xishen before the old place of memories to meet.If you can't see you, wait another 10 years, become an old woman and I will wait for you, so if you have time, come and see me, to the favorite Asasa, November 24th, 4th year class A, Kinoshita...\" Xiaobai looked at the postcard in his hand and read.

\"Doctor, this shouldn't be your first love**, right?\" Xiaobai asked the doctor with a smile.

"Hehe.\" The doctor smiled and didn't answer.

\"Doctor, tell me your story, it seems very romantic.\" Xiaobai looked at the doctor with a hopeful gaze, although his eyes were slightly squinted so that the doctor could not see the pupils, but the doctor still felt that Xiaobai on the other side was waiting for his answer with anticipation.

\"This was all 40 years ago, it was the first day of school after the summer vacation, I was almost late, so I copied a different shortcut from the past, a junior girl stood there with a blue face, it was a cute girl wearing a hat, under the brim of the hat was a cute girl with big watery eyes, it seemed that there was a dog barking in front of her, and she didn't dare to walk over, it was the famous Noi family with a big dog nearby, so there was no way, so I let her hide behind me and walk over, seeing that she was afraid of being like this, I asked the reason, She said that she had been bitten by her own dog when she was a child, so she was afraid of animals.\" The doctor said with his head raised and said nostalgically, as if the man was right in front of him.

...

\"Because it was so pitiful, I took her to a friend's house with a little hamster, and at first she was scared, but gradually she became familiar with it... After two months, she began to like animals, and she was able to walk by with a smile in front of the Noi family's dog.\" The doctor continued to pause after saying nostalgically.

\"And what happened later?\" Xiaobai asked as he looked at the doctor who had stopped.

On a rainy morning at the end of November that fall, I waited for her to come over at the door of Noi's house as usual, but I didn't see her until I waited, and I was worried about whether she was sick, so I went to her house after school, but the neighbor next door told me that she had moved out that morning.\" The doctor said with his head raised and said nostalgically, but his expression was extremely lost.

\"So, did the Doctor find this postcard in the mailbox at home?\" Xiaobai asked, holding the postcard in his hand.

"Eh, how do you know?\" The doctor looked at the little white across from him in surprise.

\"Because of the name, the name under the postcard is only three words under the wood, and the back is very vague.In combination with the rainy day that the doctor just said, so I think it must be the doctor's first love ** left when he moved away in the morning, and because of this, the name behind it will be blurred because it was wet in the rain.\" Xiaobai pointed to the ambiguous place on the postcard and replied.

\"You're really good, compared to the new one.\" The doctor looked at the other side and praised.

\"And then?have you ever seen her?\" Xiaobai smiled and looked at the doctor and asked, not complacent because of the doctor's praise.

\"Oh, no, I don't remember that old place of memory.\" The doctor replied with an embarrassed touch on the back of his head and a smile.

\"Then it doesn't seem to be the Noi family or the place where the hamster house was raised.\" Xiaobai said as he flipped over the postcard.

"Huh, how do you know?" asked the doctor, looking at Xiaobai suspiciously.

\"From what you said just now, these are basically these two places, and I think the doctor should have been to these two places later, but I probably didn't see them. 4163,33,6,0,Hint,Animal.\" Xiaobai looked at the prompt on the postcard while answering his doubts to the doctor opposite.

\"Hehe, you got it.\" The doctor touched the back of his head and smiled awkwardly.

\"So the Doctor forgot that place of memory?\" Xiaobai asked as he jumped off the couch.

"Hehe.\" The doctor smiled awkwardly.

\"...\" Looking at the doctor's embarrassed smile, it seemed that he saw a trace of sadness on the doctor's face, perhaps, no matter who forgets that important place, he will blame himself very much, just like a good memory, forgotten by himself to the point that he doesn't know what to do, but this memory is the most needed and precious memory for himself, the pain that can't be remembered will make people lose it.

It seems to be remembering the doctor's appearance when he was a child, and then remembering the appearance of the doctor's youth, and then to middle age, until now, there are many things that can change in 40 years, but I didn't expect that what the doctor has never changed is that first love.

\"Doctor, don't you want to inquire about your first love?\" Xiaobai jumped off the couch, took a pen and notepad from nearby, and then returned to the couch.

\"Well, I can't even remember her name.\" The doctor replied as he looked at what was being written.

\"I think you won't forget the people who are most important to you, and even if you do, you can find out by asking at school.\" Xiaobai said as he wrote those tips on the paper.

"Hehe, but I think we'll see each other again in 10 years, so there's no need to ask.\" The doctor obviously ignored the previous one.

\"Kinoshita,Speaking of Kinoshita, I think of a person.,It seems to be a very famous one recently...\" Xiaobai wrote a name in the upper left corner after writing the prompt on the paper.

\"Well, that's pretty much it, let's see if I can remember.\" Xiaobai handed the notepad to the doctor.

"Hmm...\" Dr. took the notepad handed over by Xiaobai, looked at the hint on it, and was stunned when he turned to the name above, as if he missed it very much.

\"Under the wood... Fusa-e.\" The Doctor whispered as he looked at the name on the notepad.

\"Well, it's the president of a fashion brand company that came out recently, the trademark...\" Xiaobai replied as he stopped to look at the doctor.

I saw the doctor reading the name on it, and then stared blankly, not listening to what Xiaobai said at all.

\"Doctor.\" Xiaobai shouted loudly.

\"Ahh What's wrong?\" The doctor woke up and looked away from his notepad to look at Xiaobai.

\"Doctor, let's unravel this hint, if you don't get it, you can see your first love again**.\" Xiaobai shook his right index finger.

"Well, no, it's been 40 years, maybe she's married.\" The doctor said, putting down the notepad.

\"Ah, Ah, ah, if people are still waiting for you according to the agreement, it's been 40 years, I think the doctor should have been waiting.\" Xiaobai waved his hand and looked at the doctor seriously.

Dr. "...\" surprisingly didn't answer.

\"The only thing we know now is that the hint is an animal.If you think of it this way, then it's dog and hamster, right, Doctor?\" Xiaobai took the notepad and said as he ticked the hint.

\"Well, I remember that's true.\" The doctor replied after a moment's thought.

"So, Doctor, did you ever have any animals in elementary school before?\" Xiaobai continued to ask.

"Well, it looks like she used to have chickens, and I remember that she liked to take care of the chickens at school.\" The doctor replied nostalgically.

\"So, add a chicken...\" Xiaobai wrote the word chicken on the back of the notepad.

\"Then let's go ahead and try to write their address, Doctor, I'll have to leave this to you.\" Xiaobai wrote the elementary school under the chicken, and then gave the rest to the doctor.

"Well, I remember...\" The doctor thought as he took the notepad and filled in the keywords he had done.

\"Then, there is a 0 in the code, if 0 means none, the doctor also said that she was very afraid of animals at first, so the 0 of the code may be her home.\" Xiaobai took the notepad, wrote the three words under the wood, and then wrote 0 below.

\"But, it doesn't seem to have anything to do with the code.\" The doctor said, looking at the words on the notepad.

\"I remember the Doctor said that one of her relatives was a foreigner.\" Xiaobai asked the Doctor after a moment's thought.

\"Well, yes.\" The doctor replied.

\"If it's a foreigner, then the animal is in English, hehe, this, doctor, I still have to trouble you.\" Xiaobai pushed the notepad to the doctor.

Dr. "...\" took the notepad and wrote down the name of the animal in English.

\"Well, it doesn't feel like it, so...\" Xiaobai thought as he looked at his notepad.

\"Their work and rest habits, too, shouldn't, what do animals have in common?"

"What do we have in common...\" The doctor touched his chin as well.

"By the way, the common denominator is sleeping.\" The doctor said as he slammed his right hand into the palm of his left hand.

"Perhaps, scream?\" Xiaobai asked, looking at the doctor.

"Scream?\" The doctor looked at Xiaobai suspiciously, and then fell into thought.

\"Well, for example, translate all the sounds of these animals into English.\" Xiaobai pushed the notepad towards the doctor.

\"That's the squeak of the rat... S...\"The doctor wrote the first name and fell into thought.

"It seems that it is very likely to be a scream.\" Xiaobai looked excitedly at the English name written by the doctor.

"Oh, it's a coincidence, if that's the case, how do you explain the previous 416333? after all, animals don't have such long calls.\" The doctor said as he listened to the pen in his hand.

\"So, if we take all these numbers apart, 6 represents the hamster in the doctor's memory, that is, the Butterfly family written by the doctor.\" Xiaobai pointed to the hamster on the notepad, then pointed to the hiragana of the Butterfly family written on the notebook, and after taking the doctor's pen, he wrote a 6 underneath, and then wrote 0 on the home under the wood.

"Take, chicken and dog...\" The doctor thought as he looked at the notepad, then picked up the pen and wrote.

"cock-a-doodle-doo: chicken, bow-bow: canine" Dr. read as he wrote down English on his notepad, then looked at the notebook as if he had seen something unbelievable.

\"4,1,6,3,3,3,In addition to the 6 of the mouse, by the way, it turns out that 0 means that there are no animals in the house under the wood, that is, there is no sound, so it will be 0.\" Xiaobai looked at the notepad and suddenly realized.

"Well, it can't be that coincidental.\" The doctor replied with a smile, but a look of anticipation could be seen in his eyes.

\"So, let's connect these.\" Xiaobai looked at the smiling doctor and took the notepad and wrote something.

\"4163 represents the chicken, that is, the elementary school, the dog represents the Noi family where the doctor went, then the butterfly family that raised hamsters, and finally the Kinoshita family without animals.\" Xiaobai read as he arranged the order.

\"That's elementary school, Noi, Butterfly, Kinoshita.\" Xiaobai wrote the name on a notepad and put it on the table.

\"If that's the case, no,i (Noi), cho,no (butterfly), under the tree can be associated with under the tree.\" Xiaobai thought as he filled in these keywords.

"Under the (no) ginkgo (i,cho) tree of the elementary school.\" The doctor exclaimed in surprise as he looked at the notepad.

\"So what did the doctor think of?\" Xiaobai asked as he looked at the surprised doctor.

"yes, I remember, I remember when her hat was blown away by the wind, and when I picked it up to give it back to her, he hugged his head and said, "Don't look, because my hair is weird, because it's different from everyone else\" and she started crying.\" The doctor said with a smile and a nostalgic smile.

\"What about later?\" Xiaobai asked with a smile as he looked at the doctor he missed.

\"Later...\" The doctor looked up, as if thinking of that time.

I said, "Yes, but I like it very much," and picked up the ginkgo biloba leaf and replied to her, "Look, it's like a ginkgo biloba, how pretty\"\" The doctor smiled as he touched the back of his head.

\"Hey.\" Xiaobai looked at the doctor with a malicious smile.

"What, what's wrong?" asked the Doctor, blushing.

"The Doctor will blush too.\" Xiaobai teased the Doctor.

The doctor smiled awkwardly, then picked up the notepad and looked at the final answer on it.

"Under the ginkgo tree in elementary school.\" The doctor whispered, as if he missed the place.

"Doctor, let's put it this way, and the appointed time is November 24th next year. (The current time is May, and Xiao Ai's appearance is also the second year)\" Xiaobai jumped off the sofa, took two cups on the counter and walked to the refrigerator.

\"yes, next year.\" The doctor said, looking up.

"Huh, why did the music stop?\" The doctor looked down the quiet hall, then at the CD that had stopped playing not far away.

"Let's have a glass of orange juice.\" Xiaobai put the cup in front of the doctor.

"Oh, thank you.\" The doctor picked up the orange juice that had been placed on the table and drank it.

\"So, Doctor, will you go next year?\" Xiaobai walked over to the DVD and changed to another Beatles CD.

"Well, it's unraveled, but I'm not sure if it's this place, and even if it is, maybe she's married.\" The doctor said, putting down his glass.

"I think this must be the place.\" Xiaobai's voice reached the doctor's ears along with the melody of the music.

\"I just wanted to say, I've always thought the name Kinoshita Fusa is familiar, right.\" Xiaobai said as he listened to the music.

"Hmm.\" The doctor nodded.

"That's because I read a magazine at Uncle Maori's house that introduced Kinoshita Fusae, and the leather bag she designed was branded with ginkgo biloba, so I was sure that the place must be correct.\" Shiro replied Dr. as he drank orange juice.

"Ginkgo biloba?\" the doctor said, bowing his head.

\"As for whether she is married or not, I don't think so, because there have been no reports about these things in the magazine.\" Xiaobai replied as he put down his cup and turned to the doctor opposite.

\"But that's just what the magazine says.\" The doctor replied after a moment's thought.

\"Hehe, according to my reasoning, if she really forgot the doctor's words, then there would be no ginkgo biloba trademark, that is, because she has always remembered the doctor, so she has been trying to make the ginkgo trademark famous, isn't it?, therefore, she must not be married yet, maybe...\" Xiaobai said his reasoning, as for the back, he didn't say it.

"Maybe she's been waiting for me for 40 years," the doctor whispered to himself.

"Doctor, don't be so unhappy, cheer up, don't you already know the location now, so when the time comes, hehe.\" Xiaobai looked at the doctor with bad intentions and smiled.

\"Hehe.\" The doctor looked at the smiling Xiaobai and laughed along.

"However, your reasoning skills are really strong, just like Shinichi said Sherlock Holmes, you can deduce places with just these clues.\" The doctor continued to say as he took a sip of orange juice.

\"Hehe, there's nothing like that.\" Xiaobai smiled embarrassedly as he touched the back of his head.

"I'm serious," the doctor said, and laughed as if he remembered something.

\"Hehe.\" Xiaobai continued to smile awkwardly and did not answer.

\"Doctor,I've already helped anyone I can.,Then it's up to you, Doctor.,That lady has really been waiting for you for 40 years...\" Xiaobai looked at the smiling doctor opposite, and then remembered the animation of the scene in his previous life.

It was a scene, a touching picture.
