There is a kind of people who are like drugs. Once you take a bite, it is hard to quit in this life. Bai Luoyin has lived with his confused father Bai Hanqi and his grandparents since he was a child. When he was 16 years old, his biological mother Jiang Yuan was going to remarry and marry Gu Weiting, a senior officer in the army. Gu Hai, Gu Weiting's son, has always been resentful of his father because of his mother's death. The two brothers with resistance were in the same class by chance. As time went by, they gradually developed different feelings. Bai Luoyin's classmates, especially his childhood friend Yang Meng, also played a big role in this relationship.
