Chen Tianchou woke up after traveling through time and found himself lying drunk on his sister-in-law Shen Xueli's bed. Because of his long-term undercover status and multiple identities, he developed mental problems and began to suffer from insomnia and hallucinations. Shen Xueli found him the best psychiatrist in Hong Kong - Ye Xinyi.
Through hypnosis, Ye Xinyi discovered that the protagonist had "multiple personalities." Chen Tianchou used her trick to pretend to be cured by her, but actually secretly investigated her past - discovering that her father was killed by the underworld, and she approached the protagonist for revenge.
Chen Tianchou did not reveal the truth, but instead helped her find the real murderer (who was sitting in front of Dongxing Society), and handed the murderer to her personally.
Ye Xinyi put aside her hatred, completely fell in love with the protagonist, and became his "psychological support" to help him stay calm in the upcoming decisive battle.
