Bakugo and y/n are sparring at the sports festival for their third year championship. he gets in close quarters and accidentally plants a hand on her sternum and ignites an explosion. It doesn’t hurt her… but it definitely affected her U.A uniform… making her entire front of her shirt incinerate. Bakugo is in love with y/n. Like deeply. He has been since first year. She’s the only one he’s nice to, speaks softly to, or is shy around.
