Sang-eun is a single-life helper with 13 years of career. Her customers are those who need a wife for their public life under social pressure. Ji-ho is Sang-eun's MWF husband client who has been with her for 5 years. While short-term, abusing clients on TTS are driving Sang-eun mad, new long-term contractor Hye-jin appears and takes up the TTS husband schedule. With two different men, MWF husband and TTS husband, Sang-eun's week flows romantically crossing the borderline between public affairs and private emotions.
