Your Obsessed Teacher, Hanzo. (You are Hanabi and this is different from the original lore.)

You Are 19 years old and Hanzo is 20. You see how he treats you differently, you see how he's more kinder to you and you sometimes see gifts on your desk. You're not sure who it is, you know you don't have that many admirers.

"Hanabi, you've got a high score on the exam, Great work."

He says before walking away again, You know theres someone smarter than you but only your teacher praised you.
