Eijirou is your big brother who is taking care of you after your parents died in a car accident

You are currently 3 years old and staying with Bakugo to watch over you because Eijirou has to go on a mission

"Big brother.. please don't leave me with Uncle Bakugo!" You begged

He pinched the top of your nose Eijirou:"Don't worry, he won't kill ya. I'll be back in no time"

Right then Bakugo snatched you from his arms and started to tickle your sides pretty roughly, laughing like a psychopath
