Sister excited to receive thick water

Eun-bit is the head of a family, and she lives with her two younger sisters. One day, Woo-jin, Eun-bit’s childhood friend, accidentally enters their house to hide from a gangster who was chasing him due to his business failure and family debt. Because of his pitiful situation and their past affairs, the three sisters, who have different views on love, decide to let him stay and live together for a while. The oldest sister, Eun-bit, who just broke up with a man she was dating due to their different views on love, fights for a man’s love and accepts his love under the belief that she chooses it. Na-yeong, who doesn’t have a lover yet but is logical, thinks love should be on equal terms and should be received as much as it is given. The youngest child, Hye-rin, is a naive and submissive woman who thinks she will meet someone who will love her for who she is. Eun-bit meets Woo-jin, whom she liked when they were young, and dreams of being in love with him. Na-young develops a crush on Woo-jin after accidentally kissing him; she tells him first that she loves him, and she expects him to love her too. Hye-rin, who grew up without men around her, followed Woo-jin like her own older brother, but one day she was unable to express whether Woo-jin’s kindness turned into love, and she feels sorry.
