“No way.” Kirishima stares horrified at what Denki had just done to the frosting of the cake, as he'd basically flinged the ornament messily with the knife at the surface of the treat.
“Gimme that...!” Sero whisper-yells, arriving just in time to take the knife away from Denki and quickly trying to properly coat the cake with the frosting. “C'mon, It's not so bad! I think sprinkles can fix it.” Denki smiles awkwardly.
Mina knows they are doomed when they hear Bakugo's footsteps approaching and as soon as he looks at the cake, he's dumbfounded as well.
“What happened!?”
So everyone points at Denki.
“I was gone for two seconds and now It's a fucking monstrosity!” Irritated, he marches over to the cake, as Sero desperately tries to fix the frosting.
