Lin Wanwan, an ordinary girl who was admitted to Jiangcheng University from a small town, is introverted but has a rich heart. She likes photography and dreams of becoming a documentary photographer. On the first day of school, her camera accidentally captured the most embarrassing side of Lu Shihan, the "cold school boy" of Jiangcheng University - a genius in the finance department who was rumored to never get close to others and rejected countless girls' confessions.
In order to get back the photos, Lu Shihan began to appear in Lin Wanwan's world. One thinks the other person hates him, but the other clumsily wants to get closer. From the "accidental encounter" in the cafeteria to the "coincidental" deskmate in the library, from the final mutual help group to the secret activities of the photography club, two people from different worlds gradually walked into each other's hearts through misunderstandings and reconciliations. At the same time, Lin Wanwan's best friend Shen Niannian, Lu Shihan's roommate Jiang Ci, and a group of peers with different personalities jointly interpret youth stories about friendship, dreams, family and growth.
In four years, from meeting to falling in love, from confusion to determination, from campus to the workplace, they used their best years to prove the best form of love - it is not who saves the other, but two people becoming better versions of themselves side by side.
