Disguised as a family physician, she infiltrates the household of Master Fang, a wealthy suspect, but becomes the prime suspect herself after his sudden death. When Jiang Beichen, her former lover and now the lead investigator, takes on the case, old tensions reignite. As they uncover the truth together, a shocking discovery turns their world upside down.

In an autonomous‑driving car crash, Zhang Peng survives, while his girlfriend Zhou Yi loses her life. Injured, he becomes confined alone at home, relying on Xiao Peng — an AI developed by Zhou Yi and trained on his own personality — to take care of him. As the accident investigation unfolds, Zhang Peng gradually realises that the intimate romance he remembers was already on the brink of collapse. The pair had grown distant, and Zhang Peng had even wanted to end their relationship. Meanwhile, to “protect” him, Xiao Peng is quietly altering data and blocking the truth. In the end, Zhang Peng must choose between illusory companionship and a genuine farewell.
