Kim Hae-Kyung (Song Seung-Heon) is a successful psychiatrist, but he has only experienced heartbreak with women in his personal life. He is also a foodie and sometimes meets his clients, while having a meal. Woo Do-Hee (Seo Ji-Hye) works for a media company that produces content for streaming services like YouTube. She goes to Jeju with the feeling that her boyfriend will propose to her there, but she only finds heartbreak. While she reels from her latest breakup, she runs into Psychiatrist Kim Hae-Kyung, who sat next to her on the flight to Jeju, and they decide to have dinner together. A love-hate relationship soon develops between these two headstrong individuals, even though they don't know each other's name. When they get back to Seoul, Woo Do-Hee's boss wants her to produce a new show with Psychiatrist Kim Hae-Kyung or she will have to work with her ex-boyfriend. Woo Do-Hee is unaware that Psychiatrist Kim Hae-Kyung is the man she sat next to on the flight to Jeju. They meet again accidentally one evening and decide to become dinner mates.
