However, it was not easy for two people with different lifestyles to live together, and Ye-hwa was dissatisfied with Hye-eun, who casually brought men. Meanwhile, Hye-eun’s new girlfriend, Hyun-seong, comes to visit at will, and Ye-hwa, who was at home alone, knows that she is a thief and calls the police when a stranger enters the house. After returning home late, Hye-eun urges Hyun-seong, “Don’t come to visit me, even if you’re not my boyfriend.” Hyeonseong, who is frustrated, confides his worries to his close brother, Kyungmin, and drinks. He tries to go back, saying that without Hye-eun, he collapses. The next day, Hyun-seong is surprised to find out that the place where he wakes up is none other than Hye-eun’s house and tries to leave, but on the way out, he sees Hye-eun and a man with a familiar face coming to the house in a friendly way.
