Five years ago, Sienna secretly donated a kidney to Julian, a rising Wall Street hotshot who was fighting a life-threatening illness. But Chloe, the cruel scheming second female lead, stole all the credit for the selfless act, and slandered Sienna as a greedy woman who took a huge sum of hush money and vanished out of sight. Carrying this unfair stigma while pregnant, Sienna left New York in total despair.
Five years later, Sienna returns to the city to get life-saving treatment for her young daughter Mia, who was born with congenital heart disease, only to land straight in the grasp of Julian, who has let his unresolved twisted love turn into seething hatred for her over the past five years. He subjects her to endless, harsh torment out of misplaced rage.
When the full truth behind the kidney donation and the secret of Mia's real parentage is suddenly exposed, Julian's entire world shatters completely. As Alexander, the domineering second male lead who is a powerful European plutocrat, makes a forceful move to protect Sienna, Julian embarks on a hell-level journey of desperate atonement to win back his family, going so far as to grovel for forgiveness, voluntarily donate blood nonstop to treat their sick daughter, and even take a bullet for Sienna. In the end, he risks his own life to save Mia, proves his unmatched devotion, finally earns Sienna's forgiveness, and the whole family of three mends their broken bond and reunites for good.
