On a rain-lashed street, Zhou Ye, a retired rowing athlete, stops a runaway tram and unexpectedly receives a lucrative offer from Linlan Associates. He becomes Gu Yanzhou's personal bodyguard.
Gu Yanzhou lives under the shadow of anonymous threats, while the unresolved case of a water accident three years ago clings to him like a parasite, gnawing at his nerves night after night. Zhou Ye sees the vulnerability beneath his suits and the way his past has left him trapped. Gu Yanzhou, in turn, glimpses the crushing guilt Zhou Ye carries over the capsizing accident that haunts him.
A contract of employment stands between them. Danger closes in at every turn. Anonymous packages, shadowy surveillance, and revenge by someone from the past come one after another. As they weather danger together, restrained feelings quietly take root.
The gulf between their social positions, the employment relationship forged by money, and the past wounds neither can heal stand in their way. When the storm passes and the danger is gone, Zhou Ye submits his resignation. He refuses to let love become an appendage to his duties.
The old ship's fog lamp, witness to their pain and obsession, never goes out. They break free from the restraints of status and contract, shed the roles of employer and bodyguard, and finally come to each other as two ordinary people, both scarred by life.
Theme: Through a meeting born of crisis, this story explores equality and self-respect in love. Love should not be built on the imbalanced relationship between employer and employee, protector and protected. Everyone must face the guilt and scars of the past. Only by casting off the shackles of status and stripping away the labels of self-interest can two wounded souls embrace as equals.
