Even though fifteen years have passed, the coach still remembers the appearance of his parents very clearly.

Father is the kind of man who is not smiling on the surface, but is very gentle behind the scenes, and is generally responsible for "singing blackface" at home. But at that time, he was only a middle school student, and he often took his father's words as a deaf ear, causing his father to sigh helplessly.

As for her mother, she still retains the wonderful existence of "girl's heart", she usually dominates TV to watch some youth romance dramas, and the domineering president department on the Internet is also her favorite.

As the only child in the family, he could have had a good life, until that terrible "accident" changed everything in his life......

So, why are you giving up on me?

Recalling the scene when his mother saw her flesh and blood blurred and began to vomit, a trace of resentment rose in the coach's heart.

Researchers in the Cold Mountain Laboratory also mentioned that it was the parents who offered to give up the treatment. Although the coach also knew that he was suffering from an incurable disease, giving up treatment of this kind of thing still made him a little uncomfortable.

What did they think at the time? If only we could get an answer.

After entering the network of room 704, the coach quickly searched for the housekeeping robot connected to wifi, occupied the robot's body with ease, turned the head of the hemisphere, and used the infrared camera to watch the surrounding situation.

I'm standing in the living room.

It seems that the decoration and arrangement of the living room still adheres to the principle of simplicity that my father likes, and there are no bells and whistles, only basic furniture.

On the coffee table is an ultra-thin e-book reader, presumably used by the mother to read romances. Although the various electrical appliances in the home have been changed for several generations, the coach has a strange feeling:

This home, as if it was when I left, has not changed much.

Like the original house, room 704 is still a standard three-bedroom apartment, with a nameplate hanging in front of the door of each bedroom, which is her mother's idea, and she thinks it is more "warm".

The housekeeping robot began to glide silently, passing in front of the door with two wooden signs, "Daddy" and "Mommy", and stopped in front of the bedroom door near the living room door.

The circular camera was pointed at the nameplate on the door, and the coach's "heart" suddenly hung up.

The words on that nameplate read "Future Star".

This shame-sounding name was also chosen by my mother at the beginning.

Of course, he remembered that he lived up to expectations and was admitted to a major university, but he suffered from deadly strong radiation during the physical examination before admission.

From that day on, as a "future star", he fell.

But why do they still keep this brand? Could it be ...... They have a new child?

The coach with a distracted mind doesn't know how to deal with a possible younger brother or sister. But the manipulator of the housekeeping robot is still held on the doorknob of the bedroom.

Now that they have stepped out of the shadow of the old days and given birth to new children, they must no longer need themselves.

In that case, say goodbye to them politely. Then leave

When I opened the bedroom door and saw the scene, the body of the housekeeping robot suddenly froze:

He always remembers the last day of his normal life, when he left home after breakfast.

And the decoration in this bedroom is exactly the same as when I left!

Leaning against the wall, next to the small bed, there are posters of basketball stars, and two pairs of sneakers are thrown not far from the desk.

The furniture in the bedroom, by the standards of 2035, can be said to be obsolete for a long time. But this room is still the same, and even the few papers on the desk are still the detectives who bought them online.

"What the hell is this ......"

The coach was distraught and manipulated the housekeeping robot to come to the desk and stare at the Agatha. Christie's "No One Left Alive."

Then, on his desk, he saw something that wasn't there at the beginning.

It was a gray envelope with his name neatly written on it, and judging by the font, it must have been written by his father.

The coach still remembers that his father was a more nostalgic man, and even in the era when mobile phone contact was already common, he would occasionally write handwritten letters and send them to distant friends.

He wrote me a letter?

The housekeeping robot stretched out its slender mechanical hand, carefully picked up the envelope, took out the folded letter paper from it, opened it and spread it on the table.

Next, he used the night-vision infrared camera of the housekeeping robot to read the letter:

My baby:

If I had known that was going to happen, I would never have let you leave the house that day.

Unfortunately, Dad didn't have the ability to predict the future.

Everyone else has advised us to have a funeral, but I'm sure you're still alive. Even if there is only a glimmer of hope, I am willing to believe it.

At that time, I was approached by a few professors who said that they could extend your life, but at the cost of never seeing each other again. I didn't take them very seriously, but I chose to give you to them.

I'm sorry, but as your father, I can't save you.

However, instead of leaving you in the hospital to rot, perhaps a scientific research institution can give you a new lease of life. At least...... That's what I think.

I often wonder if that tragedy hadn't happened, if you were still with us, you would have lived a happy life like your classmates.

Although I will often reprimand you, I also see your ability, and you will definitely not be worse than anyone else.

To this day, your mother doesn't want to believe what she saw in the hospital that day, and she's still tidying up your room for you, waiting for the day you return.

You'll be back, right?

We're all old, but you're still young. I find myself my memory is starting to decline, you'd better come back before I forget about you. Your old father has a lot of self-esteem, and I don't want you to see me unable to take care of myself.

September 5, 2030.

……

After reading the letter his father wrote to him, the slender arm of the housekeeping robot trembled slightly.

Even with the worst-case scenario, the coach didn't expect it to be like this:

Instead of leaving this painful memory behind, the parents chose to keep it forever. They even believed the words of the researchers in the Cold Mountain Laboratory, just for the faint glimmer of hope.

No matter what you become, what a horrible and incurable disease you have. They still believe you're alive and waiting for you to come back.

Because, you are their only child.

“……”

The housekeeping robot stood in front of the desk for a long, long time, until there was a sound of slow footsteps in the living room, and a somewhat old male voice was received by the "ears" of the housekeeping robot and entered the coach's consciousness:

"How did the door open?"

The housekeeping robot turned his head, the bedroom light was turned on, and a middle-aged man with a somewhat rickety back stood in front of the bedroom door and looked at him.

My father's hair was all white, his height seemed to be shorter than he had been fifteen years ago, the wrinkles on his face were clearly visible, and only his eyes were still as bright as ever.

Facing the housekeeping robot standing in front of the desk, the middle-aged man seemed to have thought of something, and asked tentatively in a hoarse voice:

"Child, is that you?"

Hearing this trembling voice, the coach felt like he was about to cry.

Fortunately, he had already lost his body, and he couldn't shed tears in shame.

He controls the housekeeping robot, synthesizes his own voice fifteen years ago, and answers the other party's question:

"Yes, Father, I'm back."
