Ye Bei, the god of war, suffered from hidden injuries and retired from the city, making a living by delivering food. Until his order-taking app had a strange update and began to receive help orders from the "parallel world". When he delivered "protection" and "warmth" to Gu Wanqing, a single mother who had the same appearance as his late lover but suffered a miserable fate, across the world's barriers again and again, the elite lawyer Gu Wanqing in the real world, who looked at him coldly, focused his suspicion on this "mediocre" deliveryman because of a series of bizarrely solved cases. When the two "shes" in the two worlds met due to the spread of the crisis, Ye Bei was shocked to realize that what he was delivering was not takeout, but the unquenchable flame of chasing his wife that burned throughout the two worlds. And he is the only fuel for this two-way crematorium.
