His hourly rate is 300 dollars. He decides the venue and menu. The client pays for the meal. These are the conditions of food therapist Kim Hae-gyeong. He is gentle during sessions and using food as a medium is highly satisfying to his clients, but he is cold when he isn’t working. Because of his personality, it is hard for him to be in a relationship and has been single for the past few years. He used to be different in the past. He used to show unconditional love like the Giving Tree, and let the woman go when she wanted to end the relationship. However, he meets a woman one day. She seems troubled for some reason and he treats her with kindness as if she were his client, but he feels himself getting comfortable around her. All she wants is to enjoy a relaxing meal with him. He agrees to it and becomes her dinner partner. Yet, he starts feeling complicated emotions for her. Deep inside, Hae-gyeong is actually a very compassionate and loving person.

She enjoys her work and life, but has one big problem. Nothing seems to taste appetizing. Her taste buds awaken when she eats with someone she is attached to. She dated two men in her 20s, but the aftermath of breakups was too big and she doesn’t like the feeling of losing her sense of taste. However, a man that came out of nowhere says he’ll become her dinner partner, and weirdly enough, she regains her appetite even though she isn’t interested in him. The dynamic incidents that occur after meeting him make her think the two breakups she experienced were nothing.
