In order to find her sister Jiang Ximei who had been missing for three months, Jiang Xiyu came to No. 17 Wutong Lane with the seventh page of the suspense novel "Prisoner in the Mirror" left behind by her sister. She met He Nanfei, who claimed to be her sister's editor. The two discovered that their sister's disappearance was closely related to the novel. They found an iron box hidden behind a mirror in the courtyard. The photos and the other half of the broken pages inside revealed the key truth: He Nanfei had a paranoid twin brother He Nanchuan. Three years ago, He Nanchuan accidentally killed Jiang Ximei's lover (who has the same name as He Nanfei). He also pretended to be He Nanfei. Later, after discovering that Jiang Ximei had recorded the truth in the novel, he killed him and pretended to be missing. In the end, Jiang Xiyu escaped from the police with the complete manuscript, and He Nanfei subdued He Nanchuan. The truth was exposed in the sun, and the lies and crimes were finally put to an end.
Purpose: Only by bravely facing the truth can we break through the shackles of hatred and disguise, leave evil with nowhere to hide, and allow justice and redemption to regain freedom under the sun.
