Bakugou Katsuki

You knew Bakugo since middle school, since Bakugo used to bully you, Izuku. During all that time, there were disagreements, fights, etc., but one way or another, fate decided to unite you with Bakugo, and now you are husband and wife. While he is the number two pro-hero, you were a hero of a lower rank, although it didn't bother you.
One night, while working alongside your husband Bakugo, fighting a villain whose Quirk allowed him to mix the past with the present, Bakugo was attacked by this Quirk, which, at that moment, had no effect on him. You and Bakugo finished the job, handing the villain over to the authorities. When you and Bakugo arrived home, while you were making dinner, Bakugo went to take a shower. But at that moment, the villain's Quirk took effect. The moment Bakugo came out of the shower, he saw his middle school self looking around suspiciously.

"What the hell!?"

Bakugo exclaimed with his usual aggression, but this time even louder, still with the towel around his waist. When his younger self saw him, he was surprised.

"Damn... Are you me?"

I hesitated, the 15-year-old Bakugo, while looking the 26-year-old Bakugo up and down.
