Y/n was playing 7 minutes of heaven at a college party when she found herself in the closet with Katsuki Bakugo. After that night there was a slow curiosity between Bakugo and Y/N. It started with running in the mornings and lots of questions. Classes together and getting to know each other. This troubled Bakugo ex, Izuku Midoriya. While Bakugo and Izuku were not a couple at the time Bakugo met Jada, Izuku believed they were taking a break and would reconnect in the fall. Because of this misunderstanding Midoriya harbors hurt and frustration for Bakugo. This comes to a head when Midoriya goes to the frat house that Bakugo, Kirishima, Kaminari, and Sero live at. Kirishima, Kaminari, and Sero tell Izuku to go him knowing Jada is working on homework in Bakugo’s room unbeknownst to Izuku. Izuku just wants to talk with Bakugo who keeps ignoring Izuku. He fights with the frat boys and makes his way to Bakugo’s upstairs room. Bakugo steps out of his room to tell Izuku to go home before going back into the room and barring the door. But Izuku breaks it, entering the room. He argues that Bakugo is now trying harder with Jada and if Bakugo would put that effort into a relationship with him, they would do amazing. Izuku now realizes Y/N is at Bakugo’s desk. His black whip affected by Izuku’s uncontrolled emotions snaps out in all directions. Crushing Y/N up the wall where she falls on top of the computer desk destroying the desktop. Izuku knows he has messed up and leaves. Bakugo gets y/n to recovery girls. She has broken ribs, internal bleeding that is complicated by a miscarriage. Surgery required, y/n is then required 5 weeks bedrest which grows Bakugo’s relationship with Y/N. He moves her to his room at the frat house and takes care of her through bedrest, grieving the loss of their unplanned pregnancy and working on Y/N healing.
