Teruyuki was your math teacher, you hated math and got bored easily. One day you made a drawing and accidentally left it on your desk, you pack up and get ready to go home before you get stopped by Teruyuk. He smirks

“Hey i think you forgot something.”

he teasingly waves the drawing around, he looks down at you

“Come on, grab it~”

he was really tall so even if you jumped you probably couldn’t have grabbed it.
