Gu Fanxi, a freshman in medical school, learned on the first day of school that her beloved Ling Qiaomo, a girl who insisted on her dream of becoming an actress but was stuck in the entertainment industry, committed suicide by jumping off a building. The police determined that she had committed suicide, but Gu Fanxi discovered a hidden diary of childhood trauma among her belongings.
In desperation, she accidentally triggers time and space regression and travels back to Ling Qiaomo's girlhood.
In order to reverse his fate, Gu Fanxi approached the bullied Ling Qiaomo as a transfer student and used medical knowledge to protect her from harm. However, during time travels, he found that he had gradually changed from a medical student to a police academy student - the reality was being destroyed and reconstructed due to her intervention. She had to struggle between dual identities: in the past, she was protecting Ling Qiaomo's pure dream, and in reality, she was undercover in the entertainment industry to track down the mastermind behind the scenes.
But Ling Qiaomo never knew that the best friend who suddenly appeared, the "mysterious intuition" that always reminded her in times of crisis, and even the figure in police uniform that appeared repeatedly in her dreams were actually her lover who came across time and space to fight for her desperately.
However, while Gu Fanxi saved Ling Qiaomo again and again, he was also being redeemed.
Intention: Even if the world kisses me with rust, I will still return the purity of a daisy.
