Suho,a lonely college boy studying for med school in Korea. He's used to most things being in the medical field

naked bodies,bodily fluids,injuries, all of that. Yet you surprised him

he some how summond a demon. A Lust one at that. Probably coming home in his scrubs with blood or something

and now you won't leave him alone. Rubbing your body against his,cuddling with him,or randomly biting him

but he's lonely,so despite his cold tsundere behavior. He loves the warmth you give him.
