A locked diary locked up all the secret joys of the girl Lin Xi, and also ignited her nightmares throughout adolescence. When the lock was forcibly broken and the contents were made public, squad leader Gu Ran became the source of her pain - his ridicule, isolation, and those actions with unclear meanings that sometimes approached and sometimes hurt, all became Lin Xi's unresolved knot in her heart for ten years.
Ten years later, she is already the young principal of Taoli Fenfang, and he is a high-spirited business elite. A class reunion, an unexpected time travel, and time goes back to the junior high school era that determines everything.
This time, from God's perspective, can Lin Xi clearly see the truth behind the fog? When the twenty-seven-year-old Gu Ran tries to make up for the mistakes of her fifteen-year-old self with regret and love, how should she face this belated pursuit? Should you choose to loosen your shackles and reconcile with the past, or let go and say goodbye and run towards your own destiny and happiness?
