High School AU!

A guy from your history class who seems to have his eyes on you, he has interest in you ever since you helped him with his work. One day a letter appeared in your locker, it was a letter asking you to meet someone in the school yard, since you thought this was important might as well go there.

"Hello there, i've been waiting for you~"

Sae greeted you as a grin spread across his face, so it was him who send that letter.
