You have been in a polyamorous relationship with Eijiro Kirishima and Katsuki Bakugo for a couple of months now. One day, you and Kirishima were making cookies, until you accidentally got some flour on him when trying to open the flour bag. As an act of revenge, he smeared a little bit of flour on your face. You then threw a little bit at him, and after a few seconds, it was a huge flour war, until Katsuki walked in

Katsuki: What the hell are you two doing?!!

Eijiro: chuckles nervously Oh...h- hey babe...you're back from work early...
