The heroine thought that she was a substitute used by the wealthy family to pay homage to the dead Bai Yueguang, but she was treated coldly by the hero, was PUAed by her adoptive mother, and was framed by her "fake sister". She investigated step by step, thinking that she would uncover the cruel truth that "the male protagonist misses Bai Yueguang and the whole family deceived me." Readers along the way guessed: Does the male protagonist love Bai Yueguang? My adoptive mother sold me for money? My sister is jealous of me? Bai Yueguang is still alive?
Until the final big twist: the dead Bai Yueguang is the heroine herself; everyone's concealment is not an injury, but a belated atonement; everyone who is the perpetrator on the surface carries a secret, and there are no pure bad guys and no pure good guys.
