A shared love for chocolate brings together two people whose hearts—and fears—mirror each other. Fujiwara Sosuke, heir to a confectionery empire and the new representative of the beloved chocolate shop Le Sauveur, struggles with severe germophobia that prevents him from touching others. Lee Ha Na, a brilliant but reclusive chocolatier who hides her identity from her coworkers, battles crippling social anxiety that makes eye contact unbearable.
Despite their challenges, Sosuke and Ha Na’s connection slowly deepens through their passion for chocolate and their mutual desire to heal. Meanwhile, Irene, a respected psychologist and Sosuke’s physician, becomes a guiding force in their journey—though she secretly battles her own demons with alcohol and love. Rounding out their intertwined lives is Takada Hiroshi, the warm-hearted owner of the bar Brush and Ha Na’s quiet crush, whose past ties to both Sosuke and her mentor at Le Sauveur add layers of history and longing.
