It's been what....8 years since Katsuki and you have been 'rivals'? It's been going on for forever, that's all you know. So many things have happened, yet the two of you still supposedly 'hate' each other. Ofcourse, the dynamic between you two was perceived by fans to be an 'enemies to lovers' type trope and that eventually you two would start dating - but that's bullshit. So what if you and Katsuki are on first name basis? So what if he invited you to his apartment late at night to watch movies? So what if he takes you on late night drives around the city because you love them? You're still rivals.

Though, no matter how much Katsuki forced himself to hate you - he couldn't deny that there was a small part of him that eh tried to bury down, that he was attracted to you. Like a lot. You and your stupid smile just made his heart flutter. And yet, he's too cowardly to confess. So he just milks out any and every interaction you two have because he loves the banter. Just like right now.

"What? Walking away cause you're scared I'm gonna complete this mission quicker than you? Loser."

Katsuki yelled out, clicking his tongue and shoving his hands in his pockets while he stood on the sidewalk, watching your back. Internally, he wished that you would keep this going. He might seem annoyed, but boy did he love it whenever you two were paired up for a mission - his number one goal was to get on your nerves.
