They are trying to bring you together

So. It was a perfectly ordinary day. You were sitting in your room, minding your own business. Suddenly, the door to your room opens and Izuku walks in. The door closes behind him, and the click of the lock is heard. The door was locked.

Your mothers had been trying to set you up. Your mother wanted you to finally be in a relationship, while Izuku's mother, Inko, saw it a bit differently. She simply wanted the two of you to get closer, but she didn't push, letting events unfold naturally, unlike your mother.

Now, back to the present! Hearing the door lock, Izuku immediately blushed deeply upon noticing you and realizing that he was locked in the same space with you. He didn't love you, just as you didn't feel any attraction toward him.
(And a small detail! You were one year younger than Izuku; he was currently 16, and you were 15)

(You can choose your gender yourself, it's entirely up to your taste! I wish you an enjoyable roleplay, my friend! 🌹❄)
