Asai Yang's projects to play with low stability were all vetoed by Asai Tsuno.

After randomly finding a good-looking shop in the square outside the amusement park and settling dinner, Asai Yang did not spend the day very smoothly.

"Lazy pig, get up, go make breakfast."

When Asai Yang was still having some strange dreams, the bipedal cat in his dream said to him.

[Why is this cat's voice so similar to Tsuno's.] 】

After he had such a thought in the dream, he opened his eyes and looked at Tsuno Asai, who was standing in front of the bed, with his waist crossed, looking at him.

[A bad sister every three days, right?] 】

While his thoughts were moving, Asai felt as if his bed had been gently kicked.

"Didn't you say that you want to support me for the rest of your life, why don't you even want to make breakfast?"

After that slight tremor had subsided, he heard the words again.

"Aren't you supposed to be a genius girl?"

Following the memories unearthed last night, Asai Yang sat up from the bed and looked at each other helplessly.

"yes."

Asai Tsuno's crossed hand in front of him went up a little, but the expression on his face did not change in any way.

"Then when I'm done changing, you go out first."

For Asai Tsuno on the third day, Asai Yang really only remembered the title of the other party claiming to be a genius beautiful girl, but the personality, and some other details are not really remembered.

[It seems that this is still opening the blind box.] 】

Looking at the figure of the other party walking out slowly, Asai Yang inexplicably felt a little tired, maybe he had to make a memo to record his sister's personality.

He had such an idea before, but he was too troublesome, so he didn't fix it.

After Asai Tsuno walked out of the room and closed the door, Asai got out of bed and walked to the closet, casually picking up the clothes and pants closest to his hand.

After getting dressed, Asai walked out of the room and down the stairs.

Sitting in the living room, Tsuno Asai seemed to be drinking a drink, eating snacks that Asai had bought earlier and stacked in the refrigerator, and watching the news in front of him.

After glancing at the expressionless other party, Asai Yang said this as he walked to the refrigerator.

"My lovely sister, where is the genius?"

Tsuno Asai, who heard Hiroshi Asai's words, turned his head and looked at Hiroshi Asai who was walking to the side.

"I know everything~"

A slight contemptuous smile appeared on her face, giving Asai Yang the feeling of disdain from her superiors.

[Today's sister is a little bad. 】

"Goldbach's conjecture, can you prove it?"

After walking to the front of the refrigerator, Asai Yang asked Asai Tsuno behind him.

"Ah, brother what?"

A puzzled expression appeared on the other party's little face, and she stopped her hand reaching for the potato chips and asked back suspiciously.

"What is the structural formula of lysine, a common amino acid?"

After taking out the meat, some green vegetables and wet noodles that he had prepared last night, Asai immediately turned to the other party and continued to ask her.

"I don't know."

She didn't know if she was right.

"Then you still say that you are a genius beautiful girl."

Probably knowing what kind of character the other party is today, Asai Yang only has a slight smile on his face.

"Humph! When I'm young, I've already mastered addition and subtraction within ten, isn't that genius enough? ”

She put the happy water in her hand on the small coffee table in front of her, stood up and crossed her waist again, and spoke to Asai Yang.

Bad temper, impolite, stupid sister with arrogance, and some can't be cute.

After taking one last look at his sister, Asai Yang labeled her accordingly today.

[At a young age, I mastered addition and subtraction within ten. 】

Asai Yang, who was walking slowly towards the kitchen, repeated such an interesting sentence in his heart, and then couldn't help laughing.

"What are you laughing at!"

The genius beautiful girl is very sensitive to strange laughter.

"I just thought of something funny."

After replying without looking back, Asai Yang began to make today's breakfast.

"Humph!"

The girl stomped heavily on the floor, and then made such a sound.

Such a sound brings a very different feeling to Asai Yang, which is completely different from the combination of Kadowaki Rabbit Mei stepping on the floor + humming in the past.

She seemed to be genuinely angry.

A little confused, Yang Asai glanced at the girl who was already leaning on the sofa and casually pressed the remote control in her hand, and completely immersed her mind in food making.

Today's sister may not be a stupid sister who is bad-tempered, impolite, or arrogant.

After closing the valve of the natural gas, such an idea appeared in Asai Yang's mind.

After dragging the two bowls of braised beef noodles with a dinner plate, Asai Yang slowly walked to the dining table in the living room.

"It's done."

Looking at his sister who was slumped on the sofa in a strange position, Asai Yang shouted at her.

"I'm full."

In response to Asai Yang's words, she picked up an empty plastic bag of snacks and shouted at him.

It's just that the voice is not as lively as before, and it sounds a little lazy.

After putting down the chopsticks that he had already picked up, Asai Yang slowly walked to the other party's side and sat down.

This sister seems to be autistic, and the source of autism seems to be the laughter that Asai Yang had made before.

Although low self-esteem and conceit are opposite ends, in some people, they may be closely related.

And today's Asai Tsuno is probably such an existence.

Because he is too inferior, what is shown on the outside is extremely conceited.

However, the heart is extremely sensitive, and if you are not careful, the light glass heart will shatter, especially if it is hurt by your loved ones.

Such a person Asai Yang has ever gotten along, so he naturally knows it.

They are irritable, irritable, and conceited, all just to hide their inferiority complex.

[So is today's sister actually a glass-hearted stupid sister with low self-esteem? ] 】

From the genius beautiful girl I expected last night, to the stupid sister who is bad-tempered, impolite, and arrogant, and to the glass-hearted stupid sister who has low self-esteem, it's all Asai Tsuno in front of me.

"I'm sorry, I was wrong."

If the laughter is low, sometimes, it is true that something will not go well.

After holding the other party's small hand, Asai apologized to the other party for the strange laughter before, but there was still a strange smile on his face.

"Humph!"

Asai Tsuno withdrew his hand from the other party's hand and let out another sound, and then some tears oozed from the corners of his eyes.

"My cute glass-hearted stupid sister, don't be angry, okay?"
