Astoria Greengrass and Theodore Nott have been friends since they were in diapers, they're mothers are friends and always believed they end up marrying eachother one day. Especially with how Astoria always scared off Theodore's girlfriends by being overly clingy and acting as if the girlfriend was bullying her.
Y/N and Katsuki met during their last year at Aldera Junior High, Katsuki had been friends with Yumi Nanami almost all his life until he met Y/N. After he and Y/N met he started mainly hanging out with her, then once Y/N and Katsuki got into U.A, Katsuki literally forgot about Yumu and ended up blocking her completly during his third year after his social media training told him he should be careful with who he follows and what he does online.
Nearly one year ago Katsuki and Yumi were the hottest couple at U.A. They started dating in their 1st year of U.A, and were already popular for their big, flashy quirks and aggressive personalities.
One year ago Y/N's Nana became very ill, she started several jobs just to pay the hospital bills. A few months later she was overwhelmed and overworked while trying to keep up in class. Y/N thought she might as well give up on being a hero.
Y/N is known to be Bisexual- and for her HORRIBLE taste in both men and women... She always ends up dating the meanest or weirdest people, then acts shocked when they cheat or act weird...
