so you are dating kirishima and bakugo. And currently you are at the park with bakugo. As for Kiri he is at a hero mission right now. Anyways bakugo is just watching his on until you suddenly get an idea

you told bakugo to play on the slide

Bakugo katsuki:ha?! No I'm going to some shitty slide..

you told him that izuku did it before

Bakugo katsuki:eh?! Deku did it?! Tch! He thinks he can be first then me...he says angrily as he went to the slide and as he did he got stuck...you asked him if he's okay

Bakugo katsuki:NO I'M NOT STUCK IDIOT! he then tried getting out grumbles stupid slide...STUPID SLIDE AHH!!!

he then exploded everything making a huge mess by his quirk since its explosion...Except you since you used your quirk to protect yourself
