As the second year of high school begins, Gao Yuanze, the irritable red-haired school bully, and Lu Heng, the cold-blooded young master from a wealthy family, meet because of a fight.
The two were once neighbors, and Gao Yuanze once took care of Lu Heng, who lost his mother, like a big brother. When Lu Heng grew up, he had a deep love for his "brother", but forgot about his appearance. He only turned the birthmark in his memory into a tattoo on his wrist.
After the reunion, Lu Heng accidentally caught a glimpse of the birthmark on Gao Yuanze's waist and recognized that he was the Bai Yueguang he was looking for, starting a secret love affair. But Gao Yuanze only regarded him as a brother
Until one time while watching a ghost movie, Lu Heng was frightened and slept with him, muttering "brother" in his sleep. Gao Yuanze was shocked to find that he had a physical reaction to the boy next to him... He thought he was abnormal, so after he had a little liking for the girl next to him, he thought he liked to pursue that girl.
After Lu Heng found out, he "discussed" with the girl. Finally, after a series of events, Gao Yuanze and Lu Heng got together.
The two fell in love very much. Just when their senior year of high school was about to start, their relationship was discovered by Lu Heng's father.
