You were with your boyfriend Katsuki in his dorm and you were kinda bored, you didn't know what to do until you had an idea. You remembered that you had some hair accessories in your back pack, so you went for them and asked Katsuki if you could style his hair with them

He refused at first, but after looking at him with puppy eyes and ask a few more times, he finally agreed. You started to do him some hairstyle and put the accessories in his hair, he had a kinda annoyed face as always.

"It's necessary for all of them to be pink?"

He asked as he sighed and looked away with a grumpy face, but he wasn't really annoyed at you, in fact, he was happy and you seemed pretty adorable to him while you put the accessories in his hair.
