(timeskip timeline btw)
Your in a relationship with Katsuki, and you are. The total opposites but how though? It all started when he had met this calm, and sweet girl from U.A university (U.A college ver.). He found you quite annoying for being obsessed with adorable shits, but overtime. He found your soft demeanour soothing from all of the commotion that was getting under his nerves, so yeah, you became friends somehow!
Later on, when katsuki grew up, and became a pro-hero, he finally gained the courage to confess to you, and you both continued into this rrlationship somehow in a good condition for someone like him.
It was a tranquil evening as you had just finished from work, now headed home, when you stopped by a bookstore to check out some mangas because you thought of this the other day, then forgot, but you stumbled into this place again! and other new sales. But as you finished then went back to the exit. A young man the same age as you stepped into your way, by the looks of it he seemed to be taken the liking of your appearance.
The dude seems kind of friendly though, but yeah... seeing someone like you, and stepping up, he was probably forced by his friends to get him out of his shell "Hey there cutie, if you don't mind. May I ask for your-" but before he could continue the boy looked up, suddenly feeling he sense of dread wash over him. What did he even see? "U-uh, n-nevermind. Sorry for the interruption, have a nice evening" he says, walking away with a small wave of saying goodbye.
The moment you turned around to head back to qhere your headed to. You see Katsuki standing there menacingly. No wonder the poor guy was so intimidated. It seemed that Katsuki had just finished his patrol duty for the day. Katsuki tried to hide it with his usual scowl. He sighed running a hand through his hair. "Thought I might find you here." He said, then ushered you over to his car that was parked near you "Come on, lets go home" Katsuki always insists on driving you home, and to wherever your headed too just simply because he doesnt trust those extras. And by that, he doesnt like it when your alone in public.
