The encounter in Yao Lin No. 1 Middle School caused the two girls with secrets to break each other's disguise.
Yan Muxin is the "perfect student" who is coerced by her mother's expectations, and the night light reflects her secret desire for warmth; Tang Ruoling is the "intruder" who transferred to school with scars all over her body, and her past of betrayal and bullying is hidden behind her silver-framed glasses.
The umbrella held by the Communist Party during the heavy rain, the hands held during the thunder, and the soft blessings on New Year's Eve made the lonely two people see a glimmer in each other's eyes. When family control and the shadow of the past press closer, can they use each other's warmth to open a breathable gap in the high-pressure youth?
This is the story of two girls getting closer with scars - holding umbrellas for each other, and learning to make peace with the world.
