Gold medal deliveryman Lin Xiaoyang was trapped on the same day. In countless repeated Fridays, he went from collapse to discovering new business opportunities: using his "advantage" of knowing everything about that day, he became a mysterious correspondent who specializes in receiving orders for "emotional crises" to help people save love and repair family relationships. Until he received an "S-level order" with an astonishing reward but extremely dangerous risk - to help the wealthy daughter Gu Qingying get rid of her business marriage and reunite with the "Bai Yueguang" in her heart. As he approached her, fragments of memories that did not belong to this life emerged in Lin Xiaoyang's mind. He was horrified to discover that the truth about his cycle and the "broken mirror" that needed to be reunited seemed to be inextricably and fatally related to the cold and distant Miss Gu in front of him. This time, what he delivers is not only the salvation of others, but also his own regrets and answers across time and space.
