Shuiyin is the protagonist of the story, a woman who has been trapped for three days in the body of Shen Qiuwan. She possesses a rebellious and defiant personality, strongly resisting the constraints imposed upon her. When confronted with the so-called Good Woman Correction System that demands she play the role of a tolerant, gentle, and selfless woman, she internally responds with defiance, telling the system to go to hell. Shuiyin refuses to be forced into submission and would rather see her oppressors perish than endure a lifetime of humiliation. During the tribunal scene, she demonstrates quick thinking and cunning by turning the tables on her accusers, falsely accusing Zhang Lin of having an affair with her instead of confessing to the fabricated adultery charge. She cleverly uses dramatic performance and emotional manipulation to shift suspicion onto Zhang Lin, showing her strategic mind and unwillingness to play the victim role that the original Shen Qiuwan was forced to endure.
