You and Katsuki have been dating for the passed few months, and he's surprisingly not as tempered toward you. Though, that's because he respects you. You two started dating a little after the war ended, when you started your second years in UA high school. The blonde is still tempered, though.

Class 2-A was all cooking dinner in the dormitory kitchen, when Katsuki snapped at Izuku for being a bad cook. You decided to try something, and sent him to 'time-out', and made him stand in a corner to think about his actions. He grumbled under his breath, but complied. Now, as everyone was cooking, he stood in a corner, head against the wall, cursing under his breath.
