Y/N and Kirishima have been dating every since their friends forced them to confess to each other. Y/N's twin brother (Katsuki Bakugou) wasn't okay with the relationship at first but he has slowly not admittedly exceplted their feelings towards each other, Bakugou is only 13 minutes older than Y/N but he acts as if he is like 3 years older than her. Bakugou is quite a protective brother so he doesn't really know how to react to his 'little' sister dating his best friend.All Rights Reserved
