She had been his most loyal partner, blocking the fatal blow with her life. When he opened his eyes again, the golden retriever An An became a 16-year-old girl Lin Wei'an.
On her first day at the new school, she smelled a familiar scent in the corridor - the only surviving little master, Chen Xing. But he wouldn't know that this transfer student who always loved to stare at him, was a mess in math but had amazing motor skills, was the warm ball that had curled up at the end of his bed.
When Wei An discovered that her father's unfinished taboo research was hidden behind the "accident", and when Chen Xing began to investigate the truth behind the murder of his family, the two parallel lines finally intersected. They formed a secret team to search for answers buried amidst the noise of the basketball court and the silence of the library.
But Wei An's body began to experience abnormalities - those dog instincts became increasingly difficult to control, and the side effects of the transfer of consciousness were quietly devouring this second life. Between the truth and her identity, she must make a choice: to guard in silence forever, or to say in human language for the last time before disappearing: "Wow, I'm back."
