Chapter 3: A Sister's Feelings

A Sister’s Feelings

“Enough already.”

I had been listening in from the sidelines, observing the situation, but I couldn’t hold back any longer and interrupted.

Yuki, who now seemed to have lost all emotion toward Yuna-chan.

No matter how much Yuna-chan tried to reach out to him, it was useless at this point.

It was like striking a drum that would never produce sound.

“Why? Mizuki-san, you said you’d support me… Was that a lie?”

It was true. Before Yuna-chan confessed, she consulted me, and I told her I would support her.

But that was because, at the time, Yuna-chan cherished Yuki as much as I did. She cared for him deeply, and I could feel that she truly wished for his happiness.

But now, the Rindo Yuna standing before me…

“I’ll be blunt. What part of you is worth supporting now, Yuna-chan? You’ve let yourself be swayed, had a relationship with a senpai, and now you’ve become someone who lies without hesitation.”

“No… that’s not true!”

“What’s not true? Were you forced into it? Were you drunk and unable to think clearly? Or did he blackmail you?”

I fired off my questions in rapid succession.

Yuna-chan flinched, unable to respond, and fell silent.

Then, when she finally opened her mouth, what she said was worse than I expected.

“I did try to refuse at first… but Senpai was forceful—”

“Then you need to file a report.”

“Huh?!”

“If you were forced into it, that’s a crime. It might be painful, but you have to report it to the police.”

Yuna-chan immediately rejected my suggestion.

“N-No! I-I don’t want to make such a big deal out of it!”

I already knew—her refusal was just a front. If she had truly been forced, she would have felt repulsed, not hesitant.

She might have even developed a distrust of men.

And if she were truly hurt, I doubted she could dismiss it so easily without any inner conflict.

“…You know the truth, don’t you? That you accepted it of your own will.”

I wasn’t angry that she let herself be swayed. It was the way she handled it that I couldn’t forgive.

“I’m not blaming you for changing your feelings. I just can’t accept that you didn’t handle things properly.”

It’s natural for people’s hearts to waver. But that’s why it’s important to do things the right way, especially when real feelings are involved.

“No… It was just a moment of weakness! The only one I truly love is Yuki!”

Her feelings, which would likely never reach Yuki again, were probably real.

But precisely because they were real, there were things that couldn’t be forgiven.

And she was the only one who didn’t realize that.

There was another truth overshadowed by Yuki’s presence.

“Then tell me—why did you give in? Would you really sleep with someone you don’t love? Are your morals so loose that you’d do that with just anyone?”

Yuna-chan wasn’t the type to cheat unless there was at least some affection for the other person.

“Of course not…”

“Then doesn’t that mean you were starting to like him, even if not as much as Yuki?”

“…Yes, maybe so.”

“Then all the more reason you should have sorted out your feelings before it got to that point. Right now, you’re just looking back because Yuki called out to you.”

Otherwise, she wouldn’t have broken her promise to Yuki, gone to see the other guy, and even taken things that far.

“But I can’t bear to be apart from Yuki…”

“That’s just selfish. You found someone else you liked, but you still want Yuki by your side? That’s way too convenient. Unless Yuki is okay with it, of course.”

A so-called reverse harem. If everyone involved agreed, I wouldn’t deny it.

But Yuki wasn’t the type to accept something like that.

I glanced at Yuki to confirm.

He had been listening to our exchange as if it didn’t concern him, but when our eyes met, he shook his head.

“That’s his answer. Yuki rejected you. So you need to take responsibility for your actions and go to that Senpai. The way things happened was awful, but Yuki forgave you.”

That’s right. If she betrayed Yuki for someone else, then she had to prove that person was worth it.

But Yuna-chan still couldn’t let go of her years of feelings and clung to Yuki.

“…Yuki, is it really over?”

“I’ve told you already. Even if it was just a moment of weakness for you, to me, it was a serious betrayal. And I don’t trust people who betray me. You, of all people, should know that about me.”

Yuna-chan should have known.

If she had realized the meaning behind Yuki’s words back then, maybe they could have at least remained childhood friends.

“No way! That’s too cruel, Yuki! Are you really going to throw away everything we’ve built so easily?! Was our bond really that shallow?! No, there must be a way to fix this!”

But Yuna-chan, still blind to the truth, lost control of her emotions.

She screamed in frustration, digging herself deeper.

“…Then tell me. How can I trust someone who trampled on our years of memories and betrayed the person they loved most?”

After a long silence, Yuki spoke, his voice devoid of emotion. That’s when Yuna-chan finally understood.

“Ah… I…”

The more she professed her love for Yuki, the more she proved how easily she could betray it.

Maybe she had assumed Yuki would forgive her, that he would always take her back.

But she should have known. Once Yuki stopped caring, even family meant nothing to him.

And yet, back then, Yuna-chan had promised to stay by his side, even knowing that.

That’s why I had swallowed my own feelings and supported her.

I had believed in her.

And this was the result.

“Yuna-chan, thank you for everything. Thanks to you, Yuki started smiling again. I’m grateful for that. But this is as far as it goes.”

I suppressed my emotions and gently told her. Because in the end, Yuna-chan was just a normal high school girl. Maybe being Yuki’s partner had simply been too much for her.

“That’s not true…”

“You know it too. Yuki will never feel anything for you again. If you keep pushing, you’ll only hurt yourself more.”

It was unfortunate that she betrayed Yuki. I was still angry.

But I didn’t believe all her feelings for him had been a lie.

They just wouldn’t reach him anymore.

Maybe now she could finally free herself from Yuki’s hold and find normal love. That’s what I truly wished for, as his sister.

And I also realized something—if Yuki was truly important, I couldn’t leave him to someone else’s care.

“…I understand. Yuki, I’m really sorry.”

“It’s fine. Just be happy with your Senpai. Let’s just say we broke up amicably. Next time, don’t cheat—handle things properly first.”

His voice was empty, stating only the facts.

For someone who truly loved Yuki, these words were the cruelest rejection.

After all, not only was he told that he no longer had any interest in her, but he also warned her as if she were the kind of person who would make the same mistake again.
