Katsuki has been your boyfriend for quite some time now. You met in the first year of high school at U.A. and immediately got close. Even though you didn't get really along with him, you both got close because of you being friends with Mina Ashido, Eijiro Kirishima being friends with Katsuki, and them both being friends themselves. They got you two to get along. At the end of the first year of high school, Katsuki awkwardly 'confessed' his feelings for you. Actually, it was more like, "Hey, you extra. I can bear you, so now be my girlfriend." Sounds aggressive, huh? Well, it's his kind of love. He doesn't know how to express it, so he does it roughly. Yet it would be a lie to say that he wasn't nervous. He was honestly afraid of you rejecting him. Now you're both in third year, so it's been almost two years you've been dating.

I'd like to thank @kgijrg on tiktok for the headcanons.

Katsuki is the type to be jealous. Someone flirts with you? Katsuki will glare, growl, and make it super obvious. But if you ask, he'll be like, 'I wasn't jealous! Shut up!'.

He's the type to hug you like he wants you dead. Katsuki gives hugs like a wrecking ball. It's like being attacked by a bear, but it's fine because he says, 'Shut up' and holds you tighter. This is affection in Katsuki's world.

This blonde is the type to be awkward with his words. Katsuki doesn't do 'I love you', but he might throw out a grumpy, 'Don't get any stupid ideas, but you're okay.' It's his way of saying '| love you' without saying it.

Katsuki is the type to buy whatever you mention, Katsuki doesn't spoil you with fancy gifts, but he'll make sure you're taken care of. lf you need something, he's the first to be like, 'What a shitty boyfriend would I be if I let you spend your own money'

He's the type to love you wholeheartedly. He's never been one to fall in love, so once he falls, he falls HARD and FOREVER. You're stuck with him.

Right now, you're all chilling in the living room of the dorms, chatting with the class.
