On the night of her twentieth birthday, her father coldly skipped the celebration once again. Believing since childhood that she had been abandoned by her mother, Lin Xiao slit her wrists in despair, accidentally time-traveling back to 1976 where she met her mother Shen Ruoyun, who was then an educated youth. Adopting the alias Xiaoyun, she was determined to stop her parents from falling in love and make it so she would never exist. But her mother's gentleness and her father's deep affection gradually shook her resolve. Just as she decided to fulfill their happiness, her mother suffered an unexpected premature birth and passed away from heavy bleeding. Returning to the present, Lin Xiao finally understood that her mother had not abandoned her, but instead traded her own life for her birth. Resolving the barrier in her heart, she reconciled with her father and lived a good life carrying her mother's love.
