Her parents disappear, saying they are chasing her missing uncle, and Cheong-ah is suddenly left living alone in an empty house. But Cheong-ah isn’t the only family to be scammed! The largest cult in the district, the Millennium Adventist Church, was also completely fooled by her uncle. And then, the leader’s son, Yohan, shows up at Cheong-ah’s house. He barges in with all his luggage…! God, is this cohabitation okay?
