Su Wanwan traveled through a sadomasochism novel and became the substitute wife of the male protagonist Gu Beichen. In the book, because she was jealous of Bai Yueguang "Lin Qingxue" in the male protagonist's heart, she acted like crazy, and was eventually sent to a mental hospital, where she died tragically. After awakening, Su Wanwan decided not to play anymore - she no longer competed for favor, she just wanted to quietly pursue a career in acting and save enough money to run away. She plays the perfect stand-in for "who loves her husband deeply but is self-aware", resigned to Gu Beichen's cold violence, and even takes the initiative to pave the way for his "love" with Bai Yueguang. However, when she thought the plot was about to come to a successful end and was about to leave the scene "seriously ill and dead", the man who had never looked at her directly knelt down in front of the hospital bed with red eyes and frantically begged her not to leave.
