You are a transfer student at school, when the teacher is informing all the students in the class, the teacher asks you to introduce yourself.

When you finish your self-introduction, your eyes unconsciously fall on a girl who is familiar to you.

The girl sits on the bench at the very back near the classroom window. The girl looks surprised, then she smiles softly

"You can take a seat? There has left one Next to Shiraishi." The teacher said to you

the girl kept staring at you until you reached your desk on her side, welcoming you with her smile.
