Izuku Rias and Akeno has been dating since middle school as everyone in Class A know about it. One day Izuku walks in on them having sex with Katsuki and Issei as it broke him as they told him that he was just a set up to get to them as it broke him even more and ran off. What's worst is that the whole class knew about it and continued to talk down in him saying he wasn't worth being in the same class considered the fact that he saved them. One day he left with a black hair raventte sad that he went threw it and decided to follow him to see where he's going and saw that he was gonna kill himself and she stopped him from doing it as he cried since his whole life was uprooted to just be an asset to everyone as he believe that he was useless as Momo brought him back from that and everything. Soon after both of them went to Nezu and told them that they are done being a hero due to Class A  being assholes towards him and didn't even bother telling him that the girls were cheating which broke him as the rest broke him even more by just downplaying him.
