When Lin Xiaoman entered the second year of high school, his life seemed to have been turned into chaos. His grades were hovering in the middle, but his parents suddenly filed for divorce; the senior he had a crush on for two years turned around and confessed to his best friend; even his only hobby, painting, was forced to give up when the class teacher accused him of "affecting learning." She was like a butterfly trapped in a cocoon, confused and helpless.
Until he met transfer student Zhou Ye. This young man who always wears headphones and lives alone secretly saw Lin Xiaoman's hidden drawings in the art room. Instead of mocking her for being "not doing her job properly," he encouraged her to participate in a citywide painting competition. The two formed a "mutual aid group". Zhou Ye helped Lin Xiaoman overcome mathematical problems, while Lin Xiaoman accompanied him to find inspiration for music creation.
As the relationship deepened, Lin Xiaoman discovered that behind Zhou Ye's seemingly free and easy life was the loneliness of a single-parent family and anxiety about the future. And Zhou Ye also regained his love for life through Lin Xiaoman's tenacity. In the summer when cicadas were noisy, they accompanied each other, faced the pain of youth together, learned to accept themselves through stumbling, and also found the courage to move forward. Those unspoken ignorant feelings eventually turned into the warmest light on each other's growth journey.
