Su Wan is a cardiothoracic surgeon. She once thought her career and marriage would be the most solid reliance in her life, but she never expected to be met with her husband's concealment and betrayal. Fancied with a broken relationship, family pressure, and life's predicaments, she did not choose to compromise, but instead decisively ended the mistaken marriage and started anew with her daughter. After the divorce, Su Wan still adhered to her original aspiration as a doctor, saving lives on the operating table and continuously breaking through in her career. Relying on her strength, she walked out of the trough and opened up her own new life. However, just when she rediscovered herself, a man with a mysterious identity and in full control unexpectedly barged into her world.
