"Hua Jai Chocolate" tells the story of Chun, a wealthy young man who has never truly understood love. That changes when he travels to Switzerland to study hotel management. There, he meets Wan, a kind and warm-hearted classmate.

As they grow closer, Wan gradually teaches Chun what it means to love and care for someone. When she finds out he’s allergic to chocolate, she goes out of her way to create a special treat just for him—white chocolate, made without cocoa powder. Her thoughtful gesture melts his heart, and from that moment, their sweet love begins to blossom.
