It is a youth novel about love, growth and courage.
The story begins at the beginning of the first year of high school in 2010: Lin Xianxing, a girl from the county town, was admitted to the key class of the European-style Qianshi Middle School. She was lonely and discovered Shen Jibai, a junior high school alumnus of the next class, for the first time during the flag-raising ceremony. An episode involving borrowing textbooks made the two parallel lines begin to get closer quietly - the Rubik's Cube, the basketball game, the blue post-it notes, and the guitar, all became the secret codes of their tacit understanding.
During the three years of high school, they experienced the liberal arts and sciences division, competition rejection, the death of their grandmother and good friend from a serious illness, and the anxiety of the college entrance examination. They also fell in love with each other in the skating rink, barbecue stall, hospital corridor, and guitar and ukulele ensembles. Lin Xianxing hid every heartbeat in the Rubik's Cube and the fog on the car window; Shen Jibai wrote down his favorites in the gas stickers in the drawer, birthday polaroids, hugs at the entrance banquet, and the dinner he made by himself before the start of college.
When the college entrance examination was settled, Lin Xianxing, who scored 563 points, decided to study medicine to protect her loved one. Shen Jibai, who had been recommended to Fudan University, sang her unspoken confession to her with the song "Can't Open the Mouth". From Yichang to Shanghai, I missed you for more than 700 kilometers, and the future is very long.
This is a tender love about "writing time to you", and it is also the way every teenager writes his youth as a love letter.
