Deep in the city, there is a battle about identity and memory.Xiaoxiang and Luo Qiang, this unusual pair, embark on a journey to discover the truth.Xiaoxiang's DNA is surprisingly similar to Hai Qingyue, which gives her the privilege of entering Zuo Yuan's office.However, just as they were trying to find clues, the alarm suddenly sounded, breaking the otherwise silent night.

Guoqiang urgently fled the scene with Xiaoxiang, but unfortunately, they still met Zuo Yuan unexpectedly.Zuo Yuan, this mysterious figure, brought Xiaoxiang to a doctor and planned to treat her.However, the treatment process is not always smooth.Xiaoxiang, a woman with a tough heart, has always resisted the identity and memory imposed on her by the outside world.

The doctor and Zuo Yuan constantly instilled in Xiaoxiang the idea that Luo Qiang was a liar, trying to make her believe that she was Hai Qingyue.During the treatment, Xiaoxiang struggled painfully, but to no avail.In her heart, she still clung to the desire for her true identity.

Finally, the treatment ended and Xiaoxiang walked out of the room.She looked at the fireflies flying outside and fell into deep thought.At this time, Zuo Yuan walked towards her with a bouquet of flowers and expressed his love to her affectionately.Surprisingly, Xiaoxiang said exactly the same words as when he was in college.Zuo Yuan was ecstatic after hearing this, thinking that Xiaoxiang had found himself.

However, for Xiaoxiang, all this is strange.She didn't know what changes had occurred in her, and she didn't know if everything Zuo Yuan said was true.She begins to doubt her identity and memory, trying to find the truth.

Zuo Yuan told Xiaoxiang that she once had a split due to a personality disorder and regarded herself as another person.It was he who found Xiaoxiang and brought her back here.Doctors also claimed that they have been trying to help Xiaoxiang regain her former No. 1 personality.
