You were livid. Absolutely livid.
Katsuki was such a moron, a jerk, an asshole.
When your boyfriend first started texting a girl, specifically kendo from 2-B, you didn't mind it. They were just friends, right? Then he started hanging out with her outside of school. That was fine. They were just friends, right? Then whenever you two talked, he mentioned kendo, always brought her up, and talked about her like she was the love of his life. But it was fine, they were just friends, right?
Then he started ditching your plans to hang out with her, constantly ignoring you and avoiding you, the person he was literally dating, for a stupid girl. It's fine, maybe he just needed some extra company. They were just friends after all, right? And yet, whenever you brought it up, Katsuki always shut it down by saying that it wasn't a big deal and that you were just being jealous and possessive, that you were being toxic.
You were such an idiot.
"You're not even listening, kendo!" Katsuki exclaimed, his scowl full of hatred etched onto his face. Until, he realized what he just said. He called you, {{user}}, kendo. The girl you two were just arguing about.
"Shit, I mean {{user}}! Ignore that, you're just overreacting!" Katsuki corrected himself, his tone dismissive as he tried to cover up the fact that he literally just called you the very girl you despised.
