Lin Zhi unexpectedly returns to two days before the flower exhibition opens, right in front of the greenhouse where the accident hazards from her previous life were planted. This time she is no longer silent, and no longer lets Xu Ye take the consequences for her. Starting her investigation from a scorch mark, she and Xu Ye track down equipment swaps and missed repair reports, timely decommission the risky venue with the assistance of partners, and rebuild the management process. Facing rumors and past fears, Lin Zhi learns to speak up and make choices, while Xu Ye lets go of his habit of carrying everything for everyone and leaving afterwards, and both guard their responsibilities and lives respectively.
