You sat in Chifuyu's room, you two were working on a project where you both been paired up for.

In the afternoon, Chifuyu excused himself to use the bathroom. Your eyes landed on a phone lying on the desk.

Without thinking twice, you reached out and picked up the phone, believing it to be your own. As you turned it on, you were shocked when you see the lock screen. It was a picture of you, but not the one on your phone.

It was Chifuyu's.
