After Mr. Yon left for business, Mr. Seo asks the customer to explain what happened to him. The customer says that the hotel became very busy because of Christmas, and that he still feels overwhelmed. He asks the doctor if he is doing well, and the doctor says that he is, but that he will return two days later. He says that his name is Kim Byung-woo, and he is a new doctor at the hospital. He thanks the doctor for the ride and calls him hyung, which means "hot" in the language of Korea. Kim says that she never thought of him as her younger brother, and she calls him "hyung" because of the doctor's words. She tells him that she fell asleep when she came home, and when she woke up the next day, she saw his message. She asks why he is back already, and why he was not replying to her texts. She says that her pheromone is unstable, so she shouldn't be getting her hopes up. She is glad that nothing happened, but she is annoyed that she saw him with someone else as soon as she arrived.
