Yoon-Jae is just a normal college student who lives alone...until his new neighbor, Beom-jin, moves in one floor below him. Then, things get weird. Namely, Yoon-Jae starts seeing ghosts everywhere, and they start stalking him. Turns out, a mysterious bell that belongs to Beom-jin is now tied to Yoon-Jae's wrist, and it summons ghosts wherever he goes. Unable to remove the cursed thing, Beom-jin suggests that Yoon-Jae help out with his work until they find a way to remove it. Oh, what kind of work? Sending ghosts to the afterlife, of course.
