Genius programmer Su Mu takes on a secret project: to create the ultimate VR healing program for her ex-boyfriend, Gu Yan, a top gourmet, who lost her sense of taste due to an accident and has long since broken up. She anonymously sneaked into the world she created and became the omnipotent "Chef God Mentor", guiding him to reconnect with the taste in the virtual smoke and smoke, and step by step repairing his frozen emotional memories. As Gu Yan fell deeper and deeper into the perfect taste of code construction, his taste buds in reality began to awaken, and his dependence on this mysterious mentor gradually turned into an uncontrollable heartbeat. Until he discovered that the light that illuminated his dark world of taste was the person he pushed away back then. This is a love letter written in code, and it is also a precise repair and restart of the scars of old love in the flood of data.
