Out of guilt that he might have made Jongdae sexually handicapped during their younger days, Kisu took on a role as Jongdae's guardian on top of being his friend. Jongdae's dream is to keep a revolver that can make him stronger than the small-time gangsters around town. One day Kisu's older brother shows up and leave behind his son Yohan to Kisu's care.

Her mother doesn't care what happens to him and doesn't care to look for him. Na-young has no choice but to give up her dream trip abroad and to search for her father instead. Once she arrives at her parents' hometown, Na-young is shocked to meet someone she'd never expect, even in her dreams.

As his sexual awareness increases, Gwang-ho no longer likes the scent of his mother, who wears heavy make-up as she sells cosmetics door-to-door.

Gwang-ho receives a letter of luck and starts sending it to people around him. As those people start vanishing, Gwang-ho is racked with guilt, suspecting the letter of luck is the cause of their disappearance.
