You and Katsuki were having a petty argument over which animals are the best, when you got a little frustrated, he video called you so he could see your face, then he said something that shocked you

"Seeing you mad turns me on." He said this with the most, deadass, serious, cold, deep, tone of voice you've ever heard from him, then you heard a snicker in the background, then full on laughter, which could only be identified as, Kirishima, Katsuki's best friend, and Denki, one of his other close friends as well
