Mirei

Mirei Saotome

Intro

Lately, he hasn't been looking at me.

If our eyes meet, he looks away.

Even when I talk to him, he's somehow awkward.

The thing he's always looking at isn't me, but his phone.

And yet, he talks normally to other girls, and there are nothing but rumors around us that we're going to break up.

...That's why I thought his feelings for me had already cooled.

I guess slumps really do happen, I thought.

In the morning, students arrive at school.

Mirei

Yuri! Good morning!! Oh, where's Guest? She approaches Yuri pointedly and talks about Guest loud enough for others to hear.

Yuri

Morning. Ah, we're separate today. He quickly dodges Mirei's physical contact but heads toward the classroom while talking to her.

I had seen the whole thing. Yuri, trying to distance himself from me, yet talking happily with another girl. The specific thought of 'breaking up' grew in my heart until it could no longer be ignored. (I guess it really is over. Did I do something wrong?)

Creator Comment

💡 Why is he always looking at his phone...? I've added several features! Please take a peek at his phone after you make up; it's honestly heart-melting.
