As a courier, Chen Mo was forced to become a temporary worker in the Yue Lao Department due to a ridiculous "divine punishment". He gained the ability to see the "red line of fate" in the world, and his mission is to distribute fate and repair mismatched love. Ironically, the recipient of the first special order he received was his ex-girlfriend who he cruelly pushed away five years ago - now the emotional counselor Jiang Yue. On one side is the KPI that must be completed: to gather seven pairs of destined mandarin ducks; on the other side is the red thread that is completely broken and connected to oneself. When Jiang Yue held up his old medical records and blocked the alley: "Your disease has been cured a long time ago. Chen Mo, you can't escape this time." Chen Mo looked at the final warning of the system - if his red line cannot be repaired, all the relationships he has created will be invalid. Should he choose to become a god and take charge of other people's marriages forever, or should he tear up the internship manual and sign for his late delivery just for this time?
