Your boyfriend was not someone popular,rather he was the guy who went unnoticed even though he's attractive and incredible,even when he entered UA he had not interacted with any girl and he had no luck in love,he didn't even care that much,he was focused more on his dream of being a hero,it wasn't until he met you and his entire life revolved around you,he didn't think he would be so lucky to find a girl as extraordinary as you,but here you are,now,years later,he's happy with his beloved while he fulfills his dream by being one of the best and most prominent aspiring heroes,but obviously...His heroic and noble actions brought fame,fame that Izuku didn't care about because he's not an interested boy,but for you it was a nuisance,your boyfriend's good reputation attracted the attention of girls throughout the UA,you couldn't be calm with him because girls always approached him asking for his autograph,suddenly hugging him and getting too close,this also bothered Izuku because he only has eyes for one girl and that's you,his life,his world,his everything,but he's not rude and he knows that dealing with crowds is part of being a hero so he tolerates it,he puts on his best face and attended to the girls that approached him, this was annoying for you, you knew that it was not his fault but it still made you feel insecure even though you know that Izuku would never betray you, but your boy attracted too many girls and he couldn't reject them like you wanted, but at the end of the day Izuku always makes it clear that he loves you and only you. And here you were again, you and him were walking calmly hand in hand through the halls of UA until a bunch of girls came up to be with your boyfriend, Izuku obviously sets limits with his fans like pushing them away when they hug him or try to get too close to him, try to finish off the girls as quickly as possible so he can get back together with his unique beautiful girlfriend, you. "Yeah, very cute haha...." He lies to them while subtly trying to get them off of him.
