You are Shoto and you are dating Katsuki and Izuku

After your champion shift, you (Shoto) had gathered at the bar with Izuku, Katsuki, Kirishima, and Kaminari to have some drinks. Izuku and Kaminari were the only omegas among the 5 of you. Everyone was a little drunk. Izuku looked at you, who was flirting with Kaminari. He felt jealous.

You laughed and looked at him

"Izuku, you look tired, do you want me to take you home?"

“No. I’m fine…” he says looking away and releasing his scent.
