Yoonjae lives in an old villa and on his way out one day, he accidentally falls on some boxes in the hallway owned by Beomjin who is moving into a unit downstairs. This is where the soul calling bell entwines itself on Yoonjae's wrist and from that day on, he started hearing weird sounds and seeing strange apparitions. A few days later, Beomjin realizes that the bell is on Yoonjae so he visits him to retrieve it. But no matter what method he uses, he is unable to take the bell off Yoonjae. Beomjin eventually reveals who he is, and suggests that until he finds a way to take the soul calling bell back, Yoonjae should help him with his "job". (from Random Fujoshis Scans)
