For cardiac surgeon Gu Jie (played by Yu Xiaowei), this is a black day. Someone called with vicious curses, saying that his father deserved to die. Then his father's urn disappeared inexplicably, and the ensuing car accident made him fall into the abyss of death. After everything was over, Gu Jie, who was almost amnesiac, was thrown to an isolated island surrounded by the sea. Gu Jie is a man with an extremely complicated heart, and he is full of the bipolar personality of tenacity and fragility. Yu Zhi (played by Wu Junmei) has spent 20 years in the gossip of others. This seemingly upside-down widow regards her daughter as everything for herself.

What happened 20 years ago that made people today taste the bitter fruit that they are unwilling to face...
