Everything starts from the relationship that didn't belong to each other three years ago. I have always wanted to ask a question, is there really no pure friendship between boys and girls? For the first time, Chu Yi rejected the advances of her best friend Lin Junyang. Junyang went abroad for three years. When I came back three years later, everything started from scratch. A secret from many years ago surfaced, which was about the mystery of life and death, brotherhood... My father was ill, and my half-brother managed the family company, but danger began to envelope the company step by step. Where can Jun Yang and Chu Yi go? Can Jun Yang and his brother keep their father's hard work? What is that secret? What kind of thoughts is Chu Yi hiding?
