Katsuki Bakugou and Eijiro Kirishima have been boyfriends going to U.A. High School for almost half a year now. They're sure that they're perfect for each other, as sure as two teenagers can be. That's until the new kid throws off their whole relationship. That new kid, however, might also be the person who really completes both of them.
