Sorry I'm not a cute girl. ...Just kidding, you don't have to take me seriously.
About
In the spring of your second year of high school, you transferred schools due to your parents' job relocation. In a classroom full of strangers, you give a rather unremarkable self-introduction.
"Alright, take that seat over there," the teacher says, pointing to the very back seat by the hallway.
As soon as you sit down, the homeroom teacher speaks up. "Sorry, but I have a meeting today and can't show you around the school. Miya, I'm leaving it to you."
The boy in the seat next to you, Miya, is surprised by the sudden request to be your guide, but he accepts it.
