As soon as Lin Wan transferred to another school, she was labeled as a "stepsister's substitute" - her vicious stepmother forced her to imitate her stepsister to please the family. Even people on campus criticized her as a "fake". But who would have expected that she would not follow the ancient script: the stepmother pretends to be pitiful? She directly exposed the evidence to slap her in the face; did her family pressure her to give up resources? She uses her strength to seize her own opportunities; she can even counter the troubles caused by so-called "system bugs". Lu Ze, the capable god of learning, was just a spectator at first, but was gradually attracted by her counter-routine, and became her strongest supporter from a "passer-by". When the substitute label was torn apart, Lin Wan used her strength to prove that she was never anyone's shadow, but her own light!
