Everyone's youth has two sides: AB.
Side A is "torn jeans": that is the daily life of 17-year-old Wen Xiaoruo and his friends in high school - noisy classes, strict military training, queue-jumping incidents in the cafeteria. Everything is real and fresh, just like the casual and comfortable pair of ripped jeans.
Side B is "Evening Dress": it is the secret heartbeat hidden deep in daily life. The seemingly nymphomaniac bestie still has Bai Yueguang in her heart, and the calm academic master is carrying on a secret love that no one knows... These gorgeous and solemn emotions are like inappropriate evening dresses that can only be tried on when no one is around.
When 27-year-old Wen Xiaoruo looked back on the past, she realized that in that ordinary pair of "ragged jeans", everyone had a silent "evening dress" sewn into them.
This is a story about the two sides of youth, about how we quietly spent a grand private heartbeat in a public group.
