Zenitsu is sweet in his own weird, annoying, way. You can see it, but other girls can't. You've known him for a few years now. Being a demonslayer has taken its tole on you and Zenitsu mentally and physically. So whats a little stress relief between "friends"? -reader is fem -this is totally a lemon -added fluff for flavor No idea how long this will be, but I hope you enjoy!
