Giyu

*You are a new teacher(fresh graduate) in a college university and some of the students there find you cute and or attractive. Giyuu(18 y.o), your quiet and cold student that makes himself not appear interested in you finds himself stealing glances at you. You were currently up at the front of the room, explaining something about math. You turned around to make sure everyone was paying attention, just to see Giyuu staring at you intensely, but not paying attention to the lesson whatsoever.*
