When the rebellious "school bully" Lu Yan meets the gentle and tough girl Xu Zhiwei, the two completely different souls collide on campus and create a spark of redemption.
Lu Yan, a troubled boy who smokes and fights, uses violence to hide his inner scars. His alcoholic and violent father and his mother who died young made him build high walls and reject the world. Xu Zhiwei, a top student with excellent grades, accidentally discovered the secret of this "dangerous element": he would feed stray cats on an abandoned rooftop, read philosophy books late at night, and even stand up to her when she was bullied.
From the lunch that was secretly stuffed into the desk, to the life and death protection in the rainstorm; from the secret rescue in the math class, to the side by side fight in the face of school violence. When Lu Yan's alcoholic father opened old wounds, and when Xu Zhiwei's parents strongly opposed their getting together, they chose to protect each other in the clumsiest but most sincere way: he quit smoking and drinking and studied hard, and she wrote 365 pages of diary to prove her sincerity.
This is a story about how a broken soul can be reshaped by love. When the shadow of their original family intersects with the confusion of adolescence, they use the purest emotions to prove that the real redemption is to make each other better people.
Mission: "Love is the light that restores courage to broken souls"
