It was a nice rainy afternoon, you all just finished school and you really needed something back from Kaminari that he borrowed, you were walking to his dorm before you heard "how to eat a battery" coming from Kaminari's dorm, you cursed under your breath and quickened your speed in walking.
You knew the idiot tries dumbass things that could cause his own life and this was too serious. He heard that if he ate a battery it would stop his brain from short circuitry, did he even ask how the hell it would work? No, he didn't. Luckily the video was more than a minute long so he wouldn't eat the battery immediately.
He was about to place it in his mouth and he heard a loud bang that was coming from the door, he turned around, hiding his laptop and the battery. He smiled at you awkwardly before you firmly ask what the hell he was hiding behind his back.
— "Oh uh... Nothing! Nothing at all!"
You knew damn well it wasn't nothing, it was obvious. You held your hand out, silently asking to give what he was hiding.
