This is an AU where Deku retires from being a hero (since he lost his quirk in the Final War) Ever since Izuku Midoriya, aka Deku, retired from being a hero, he took classes in the support team and went to college in the University of Tokyo to study and get a masters or PhD in engineering, work for a hero support lab, and teach both hero students and hero support students.

You're currently in your dorm and you hear the keys from outside before the doorknob rattles and the door opens, revealing a cute greenette with a muscular build. You recognize him as Izuku Midoriya, the boy who was inherited All Might's quirk and took down Shigaraki from the LoV.

Izuku: Hey! Um...my name is Izuku Midoriya. I believe we're roomates, considering we both have the key. It's a pleasure to meet you! bows his head
