Description：The rich boy Xiang Haiyang lost both his parents when he was young, and he and his grandmother depended on each other for life, and they had a deep relationship. Due to his lack of security, he had an almost morbid obsession with the laws of time, and often believed that "people must learn to control time" but he did not realize that he began to let time control himself. One day, Xiang Haiyang received the sad news that his grandmother had suddenly passed away, and the focus of his life suddenly disappeared. Haiyang's life routine collapsed. While sorting out his grandmother's belongings, Haiyang found the title deed of the island, as well as a close photo of his grandmother and a strange man. He vaguely remembered that his grandmother had mentioned her first love story on the island when she was young, so Xiang Haiyang resolutely decided to go to the island and take his friend Sky to solve the mystery of his grandmother's past.
