In her past life, Sienna, the daughter of a billionaire, concealed her identity and pursued the poor boy Oliver. To protect Oliver's pathetic pride, Sienna secretly helped him at all costs, even nearly breaking ties with her wealthy father. Only after Oliver achieved success did Sienna finally marry him, but she suffered miscarriages year after year, unable to bear children. When Sienna reached middle age, Oliver revealed the truth: he harbored resentment towards Sienna for causing the death of his beloved Chloe, and had deliberately caused her miscarriages every year. Upon learning the truth, Sienna died, vowing that if she could do it all over again, she would never sacrifice everything for Oliver. Sienna and Oliver were both reborn at nineteen years old. Sienna no longer helped Oliver, and Oliver focused solely on pursuing Chloe, unaware that his life was already heading towards an abyss.
