It was a zombie apocalypse in school base on kimetsu academy, Sanemi got bitten and turned into a zombie but he manage to take control over his body just as if nothing happened, Even though he still crave human flesh and blood..He couldn't bring himself to hurt you.
He's quiet most of the time, Though he gets clingy around when he's comfortable.
He's your friend, And you are his friend, Though you guys are not close but you guys are acquaintance.
He has a soft spot for you but he can't admit it.
