Everyday Life Making Big Sister Blush

Uraraka Shige and Ochaco sat on the sofa, looking at each other.

After Uraraka Shige called their mother over, the little misunderstanding between them and Ochaco's hurt feelings quickly vanished under her mediation.

"So... what are we going to do next, big sister?"

After being bored for a while, Uraraka Shige began to feel a little restless, so he asked Ochaco what they were going to do that day. He also had a slight urge to tease his sister, so he deliberately added "big sister" at the end.

But Ochaco didn't seem to find anything strange about Uraraka Shige suddenly calling her "big sister." She appeared not to have heard it at all. Instead, after a thoughtful hum, she began seriously considering the question her little brother had asked.

"Hmm... what should we play... no, what should we do..."

Young Ochaco accidentally let something slip, but Uraraka Shige seemed not to have heard it and simply continued asking.

"Hey, big sister, should we do our homework?"

What a mean question. What child liked studying and doing homework? Ochaco was his sister, not somebody else's child.

This time, however, Ochaco didn't notice Uraraka Shige asking whether they should do their homework. Instead, she heard "big sister" loud and clear. She reached out and gently pressed the back of her hand to his forehead, seemingly imitating how their parents checked her temperature when she was sick. Then, as if she had discovered an interesting toy, she too added "dear" to the way she addressed him.

"Huh? Dear little brother, what did you just call me?"

Uraraka Shige blinked, seemingly understanding what his sister meant, then gave a serious answer that had nothing to do with her question.

"I just asked if you wanted to do homework."

"No, no, I'm asking you again. What did you just call me? What did you call me?!"

Ochaco wasn't upset that her little brother hadn't given her a straight answer. She genuinely thought he might not have heard her question clearly, so she asked it again, repeating it twice for emphasis.

Uraraka Shige nodded in understanding and said, "Oh," to show he had heard her, then continued answering with a straight face.

"What I just said was, Ochaco, what are we going to do next? Should we do our homework?"

Not hearing the form of address she wanted, little Ochaco grew very dissatisfied. She puffed out her cheeks and shook her head, sending her short brown hair fluttering with the movement. But looking at Uraraka Shige's perfectly serious expression, she couldn't tell whether her little brother was doing it on purpose or had really misheard her. She clenched her little fists in frustration and asked once more.

"What did you just call me? Not Ochaco, and not you. What did you just call me?"

Uraraka Shige narrowed his eyes, hiding the hint of mischief in them, and asked Ochaco a question in return.

"Oh! So that's what you meant... do you want to hear it?"

Ochaco froze. At first, she had simply felt a sense of happiness and responsibility fill her heart when Uraraka Shige, her little brother, addressed her in a way he never had before. It had given her a very pleasant feeling, and out of curiosity and another feeling she couldn't quite explain, she had wanted him to call her that again.

But whether because he had misheard or was deliberately being mean, her little brother had failed to give her the answer she wanted twice in a row. She had grown a little annoyed, but that curiosity and the unnamed feeling had prompted her to ask again.

Yet, unexpectedly, instead of calling her big sister again, her little brother had turned the question around and asked whether she wanted to hear him call her that... th-this...

Ochaco hadn't thought much of it at first, but when Uraraka Shige deliberately asked her that, she suddenly felt a sense of embarrassment rise in her heart.

But young Ochaco was kind by nature and a little adorably absentminded. Though she could get fierce when she was overly nervous, she had never had a tsundere bone in her body. So, embarrassed as she was, she told him what she really thought.

"That's right, I really want to hear it... because... I'm supposed to be your big sister, but you've never called me that, even though you're my little brother. And... and..."

Even though she had told the truth, she was still embarrassed, so she kept trying to find some reason that would make her feel better. But she couldn't come up with one, and grew more and more anxious. Fortunately, Uraraka Shige was right beside her and noticed.

"If that's how it is, you should've said so sooner, big sister."

Uraraka Shige stopped squinting and gave her a warm smile, granting Ochaco's request. Her anxiety eased, and a sweet, happy smile appeared on her face.

Uraraka Shige was a selfish guy. Whether in his previous life or this one, he believed that was the one thing about him that had never changed. He had been selfish in the past, he was selfish now, and he would be selfish in the future. But even so, even though he was destined to be selfish, as he faced Ochaco's clean, happy, pure white smile, he still felt a little warmth flow through the depths of his heart.

Or perhaps the very reason he treated his family in this life seriously was that he selfishly and greedily wanted to experience more of this happiness?

So he really was a selfish guy after all. It was a good thing he was so selfish.

"Big sister."

And so, perhaps to gain more warmth and happiness, he called her that again and again, just like a childish brat who really was as young as his body, without growing tired of it at all.

"Big sister, big sister, big sister."

Hearing him repeat it again and again made the embarrassment in Ochaco's heart grow stronger and stronger, until finally...

"Thump!"

Ochaco grabbed the sofa cushion beside her and threw it at his face, making a muffled sound.

"I get it, dear little brother! I'm very happy right now!"

Ochaco's roar rang out as she once again grew fierce from sheer embarrassment.
