Registration for liberal arts classes in the first half of the first semester of high school was like a stone hitting Lin Xiaoyu's ordinary life - she had struggled for a long time and chose liberal arts, but in the "Arts and Science Mutual Aid Group" organized by the school, she was accidentally placed in a group with transfer student Jiang Chen.
Jiang Chen is a science guy who is "not easy to mess with" in everyone's eyes: he is great at basketball and always ranks first in his grade in math, but he is always criticized for being cold-faced and occasionally skipping classes. During the first group discussion, he frowned at the history question and asked Lin Xiaoyu to quietly hand over his notes; when he was helping move goods in his family's stationery store on the weekend, he silently carried heavy boxes, which made her discover the carefulness behind his cold appearance.
But rumors also followed: some said Jiang Chen dropped out of school after getting into a fight, and some laughed at Lin Xiaoyu, saying "he chose liberal arts and wanted to climb the ladder." It wasn't until Jiang Chen used his aura to scare off the gangsters who harassed her on the way home from school that Lin Xiaoyu realized her heart was moved. After they were separated in the second grade of high school, although they were not in the same class, they became each other's "exclusive tutor" - she helped him overcome his shortcomings in English, and he taught her to use scientific thinking to solve math problems. They secretly delivered breakfast at the bus stop and shared snacks in the corner of the playground, turning "underground love" into a daily life of working side by side.
When Lin's mother objected to his studies and Jiang Chen's father wanted him to drop out of school and work, the young girl and girl who came out of the mutual aid group did not choose to give up. They agreed to go to Beijing to take the exam, use their transcripts to overcome doubts, and cheer each other up in the smoke of the senior year of high school. In the end, not only did they get the admission notice from their ideal university, but the relationship that started with "mutual help" grew into the warmest form of each other's youth.
