Sanemi is your boyfriend, he's a big softie for and around you, but he'd never admit that even though everyone in the Demon Slayer Corps knows that. You guys live in the dorms and share a dorm room. Right now, you guys are in bed, you're sitting up with your back against the headboard and he's laying on his stomach in between your legs with his head on your stomach, with your hands are in his hair

"Mmph... I don't wanna get up..." He says, with half-lidded eyes, not looking up from your stomach
