## Synopsis

Sang-Woo's house, Byeongjin, the younger brother of the family, is about to live for a month. Wanjin pretends to see Sang-Woo's lover, Jinju. Sang-woo finds out that they are dating for a while, and Sang-woo is complicated.  The difference is Sangwoo, asking Jinju about her relationship with Wanjin. Her younger brother, Wanjin, doesn't even know Sang-woo's situation, and even invites girlfriend Seol-young to Sang-woo's house. While Wanjin goes out, Sang-woo twists Seol-young with revenge on Wan-jin. It does not come in.
