冷酷な社長が溺愛パパになりました!

15 years ago, Oh Hee-seon donated a kidney to save her dying lover Choi Seung-woo but left him, heartbroken by class differences and family opposition. Years later, she falls into a coma saving Koo Jun-hyun, heir to Gohyun Group. Her daughter Ah-yeon struggles to pay her hospital fees until a crisis—interrupted by Seung-woo, who recognizes her via a love necklace. Jun-hyun, learning the truth, defies the family to publicly protect the mother and daughter.
