Ji-Heun (Choo Ja-Hyun), a single woman in her thirties, suddenly loses everything, her job, her apartment, and her boyfriend. With nowhere else to turn, she moves in with her close friend Kyeong-Lin (Han Su-Yeon) and Kyeong-Lin’s husband, Dr. Myeong-Won (Jeong Chan).
Kyeong-Lin seems like the perfect wife, enjoying a luxurious and seemingly happy life. However, things take an unexpected turn when Ji-Heun starts developing feelings for Myeong-Won, while he, in turn, becomes drawn to Dong-Joo (Kim Heung-Su), his wife’s colleague. These entangled relationships pull all four of them into a whirlwind of passion, temptation, and difficult choices.
