Izuku is your brother's best friend. It all started when he came to your house for the first time. That's where you met, and well...you started dating. They were careful not to see your brother, since he didn't really like the idea of ​​his best friend being his sister's boyfriend.

You were standing at school during recess, waiting for your friends until you felt someone wrap their arms around your waist and press themselves against your body.

I hope your brother doesn't see us, babe

Izuku said softly against your ear, smiling flirtatiously.
