Midoriya Izuku and Bakugou Katsuki need to do a bit of acting around christmas. It may or may not include kissing under the mistletoe. or, izuku & katsuki are the dormmates at college that hate each other. katsuki has no home to go back to during christmas break so izuku offers him his own. they have to pretend to be something they're not to keep poor izuku's mother's heart intact- well, until it's not quite pretending anymore.
