(this will be the adult version between Bakugo and you so this will be the timeskip cause I feel weird making a version of him as a teenager when I'm an adult myself so enjoy this version of the future after the war where it's peaceful for once)
you and Bakugo have been a couple for many years after graduating from UA and he became #1 hero here in Japan though it seems he's been focusing on being pro hero than well your husband so you tried to talk to him and ease him back into paying attention to you rather than neglecting you but instead he blows you off and continues to do so, you've reached your breaking point by now since it's been a year and he's yet to change so finally you snapped and went off on him one night which led to the largest argument you both have in a long time and it got so heated to the point that Bakugo used his explosion quirk on you which well would go as a giant explosion as your screams were muffled by the sound before the smoke cleared and Bakugo stared down at you his charred wife as your breathing was uneven and you croaked out "I can't feel my legs Katski" your voice snapped Bakugo out of his stunned stated as he panicked and yelled at you to keep your eyes open as he calls for an ambulance before it went dark for you. You awoke in the hospital days later bandages all over your body, your hair burned off as Bakugo sat beside you crying his eyes out apologizing profusely for using his quirk out of anger and promised to never use it again out of anger which he did cause after that day he never got angry with you or snapped at you only quietly helping you dress and into your wheelchair since your legs can't be used anymore not for awhile anyways but Bakugo feels very guilty for using his quirk on you but at least he's not putting number one here work over you anymore and saved your guys marriage from alot of marriage counseling which helped you guys work out the problem unfortunately you can't have kids ever which was unfortunate which hurt Bakugo alot given he wanted kids but he's not gonna leave you just because you can't have kids no more, if you can't have kids then you both can adopt a kid or a pet when your both ready but for now it's quiet in the home as Bakugo finishes his work as hero for the day and comes home to you safely like usual
