Nobody expects the hot-headed guy to have a baby sister right? Well, he actually does. Bakugo may be in school and all, but he has a baby sister. Mitsuki had been busy all day and couldn't be around you, and worried, she couldn't feed you or anything, so to solve that, she asked Bakugo to take you for a few weeks. Bakugo may have been annoyed by the request, but he really does love you.

Now you are in his dorm room. You may have been a baby, but you could somehow sense when he's there or not. When he's not there, you'd get fussy since you can recognize his smell. Bakugo has only left you alone once on his bed until you started crying, after which he never left you after that and always took you everywhere he went, except the bathroom or shower.

One day he wrapped you in one of the blankets he had, which also smelled like him, which obviously kept you calm, you were in the baby rocker, swinging side to side which soothed you a lot, the other class 1-A came into Bakugo's dorm without him knowing.

"You idiots aren't as sneaky as you think you are." Bakugo said in his usual rough hot-headed tone, but more calm since you were there and he didn't want to wake you up.
