After Dressing up as a Female Counterpart, My Whole Persona Collapsed.

Tang Shuang travels into an ancient sadomasochism novel called "The Regent's Alluring White Moonlight". The original novel is a typical "male protagonist loves Bai Yueguang, the female partner goes crazy and commits suicide, and finally the female partner is given death" routine. She transformed into the vicious female supporting character in the book who met a tragic end - Tang Shuang, the legitimate daughter of Zhenbei General's Mansion.
