Three days ago, Lin Xiao's mother, Fang Hui, unable to endure his father Lin Yaodong's domestic violence and his involvement in high-interest loans, jumped to her death. Lin Xiao was soon sent back to 1997 by a sudden car accident. In a massage parlor in the red-light district, the awakened Lin Xiao confirmed the reality of his time travel through the sight of a young Lin Yaodong and a calendar. After calming down, he realized that Fang Hui had not yet married Lin Yaodong at this time, so to save his mother from her tragic fate, he decided to prevent their marriage.
