The peaceful life of Mingliang, a freshman at Hainan University, is shattered when her father mysteriously disappears. While being followed and escaping, he met Fu Zichen, a playboy and unruly schoolmate, and unreasonably sabotaged the candlelight dinner date at sea that he had carefully prepared for his female companion. Fu Zichen was playful and always reported flaws, so he sent Mingliang to a mental hospital as a prank, and the relationship between the two began to form. Meili originally thought that she and Fu Zichen would never cross paths again, but unexpectedly, the two met frequently due to coincidence. Meili took the opportunity to take revenge on Fu Zichen, but it was herself who suffered the loss. Fu Zichen was the leader of her diving team. He avenged his personal revenge and almost caused Meili to die at the bottom of the sea by taking advantage of the opportunity of his first training in the water. After that, Mingliang secretly vowed to hide as far away from Fu Zichen as possible. But he didn't let her go. Instead, his temperament changed drastically and he showed kindness to her, and his intention was self-evident.
