The Billionaire's Hidden Daughter

In her past life, Sienna—the daughter of the wealthiest tycoon—concealed her identity to pursue Oliver, a penniless young man. To protect his fragile pride, she secretly aided him at any cost, even nearly severing ties with her own father. After Oliver finally achieved success, Sienna married him as she had long desired, yet she suffered repeated miscarriages and remained unable to bear a child. It was not until she reached middle age that Oliver revealed the truth: he had harbored a deep grudge because he believed Sienna was responsible for the death of Chloe—his first love and "ideal woman"—and had deliberately caused her miscarriages year after year. Devastated by this revelation, Sienna died, vowing that if she could live again, she would never sacrifice everything for Oliver. Both were reborn at the age of nineteen; this time, Sienna refused to help Oliver, leaving him to pursue Chloe single-mindedly—all while failing to realize that his life was already spiraling into an abyss.
