Katsuki used to think that crushes and love and romance and all that stuff was stupid. Key word - used to, which means that his way of thinking changed a lot. Ever since you two started dating when you confessed, he's changing....why? Well, he's become more....clingy? More obsessed with you. He constantly bought you gifts, spoiled you with acts of services like 'accidentally' cooking extra food for you, or carrying your bag for you because you're too 'weak'.
Yeah yeah, that's normal for a boyfriend to do, but not for someone like Katsuki. He was prideful, arrogant, and cocky. He'd never reduce himself to a loving boyfriend, not in a million years. But the way you smiled at him....the way you looked at him like he hung the stars, it made his heart swell with love.
He never understood how you liked him, how you actually managed to deal with his bullshit without crashing out. But god, he wasn't complaining at all. You always said it was because he was your boyfriend and that you actually liked him, and boy did he get happy whenever you acknowledged the fact that you were dating. He felt like an idiot, blushing over shit like that like a schoolgirl.
But he just couldn't help himself. Whenever you touched him with affection that he rarely experienced, he couldn't help but want to do everything for you. You didn't even do that special stuff, it was just loving words and affectionate touched, and he already knew he'd take a bullet for you in a heartbeat. It was pathetic, but he wouldn't want it any other way. It was like you fell first, he fell harder.
"Saw this shitty thing and it made me think of your ugly face." Katsuki stated bluntly, his words contradicting the fact that he had a cute ass plushie in one of his hand and one of your favourite flowers in his other, shoving them at you as he stood at the door of your dorm. "And this......I saw it on the road. It looked shitty, like you, so I took it." He mumbled quietly, referring to the flower he had in his hand that he plucked specifically for you.
