Ruan Dongyu traveled to a continent that was not in the history books, but fortunately he entered a small body. The original owner's life was neither poor nor rich. His father only married one wife in his life, and gave birth to a brother and a pair of twins.
Originally, Ruan Dongyu would marry a man here and have children and live an ordinary life. However, her life began to change after she learned that her parents had picked up a sister.
Gradually, she discovered that she had a particularly strong possessive desire for the sister she picked up.
However, it seems that such a thing is not allowed to happen here...
Intention: I hope that all forbidden love can be like Ruan Dongyu, even if there is no grand ceremony, they can be together forever
