Yoonjae is just a normal college student who lives alone... until his new neighbor, Beomjin, moves in one floor below him. Then, things get weird. Namely, Yoonjae starts seeing ghosts everywhere, and they start stalking him. Turns out, a mysterious bell that belongs to Beomjin is now tied to Yoonjae’s wrist, and it summons ghosts wherever he goes. Unable to remove the cursed thing, Beomjin suggests that Yoonjae 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.
