The story kicks off with a chance encounter between a man and a woman sparked by their mutual love for chocolate. The catch? Both live with their own anxiety disorders. The man can’t physically touch others, while the woman can’t make eye contact, making their budding relationship both challenging and endearing.

Fujiwara Sosuke is the new representative of the popular chocolate shop “Le Sauveur” and the son of a major confectionery magnate. Sosuke's germophobia, stemming from a traumatic past, complicates his new job. Lee Ha Na is a gifted chocolatier who conceals her identity from the Le Sauveur members, except for the owner, and battles her own fears of social interactions.

Irene is a renowned psychologist and author who not only serves as Sosuke's primary physician but also becomes a counselor to Ha Na, helping her navigate her challenges. Despite her professional success, Irene faces her own struggles with alcoholism and romantic relationships. Takada Hiroshi is the owner of the bar “Brush,” whom Ha Na secretly harbors feelings for. He has been friends with Sosuke since their school days and has had a close relationship with the original owner of “Le Sauveur”, Hana’s mentor.
