Ever since he was young, Bai Luo Yin (Xu Weizhou) has been living with his careless (but loving) father, Bai Han Qi, and his grandmother. When he turned 16 years old, his biological mother Jiang Yuan remarried. Her new husband is a high-ranking military official, Gu Wei Ting. Because of his mother's death, Gu Wei Ting's son, Gu Hai (Huang Jingyu), has been harboring a deep grudge towards his father. By the random hand of fate, the two step-brothers with wildly conflicting emotional backgrounds were placed in the same class at a Beijing high school, without knowing each other's background at first. With time, they slowly developed a special feeling toward one another. Their classmates, You Qi and Yang Meng, had been instrumental in the relationship.
