Cheng Chen was ill-fated. His father left without saying goodbye when he was seven, and his mother suddenly died of asthma when he was fifteen. He experienced a harsh and unfair time at his uncle's house.
Lu Nan was the first person he met.
In the Taekwondo Club of the new school, Cheng Chen reunited with Lu Nan, only to find that she and Xu Zheng had come together. One day Xu Zheng suddenly alienated Lu Nan and proposed breaking up. Cheng Chen was heartbroken and felt unfair for Lu Nan. It turned out that Xu Zheng's relationship with Lu Nan was a deliberate revenge.
Xu Zheng imitated Lu Nan's handwriting and asked Cheng Chen to go to a place where the two often met. Cheng Chen was insulted by several teenagers there, but the last thing he saw was the averting gaze of Lu Nan, whom he liked!
A disguise that was originally sunny and strong collapsed in an instant.
After many twists and turns, he arrived at a new university with scars all over his body. Unexpectedly, he would meet Xu Zheng again here.
