After Traveling Through the Book, I Sided with the Villain and Was Discovered by the Male Protagonist.

He Ting wrote a fantasy article and later made a fool of it. As a result, she was forced to travel into the world described in the novel, and she had to complete the ending of the story before she could return to reality. He Ting also has her own selfish motives - she prefers the villain she created to the male protagonist. So she geared up and decided to help the villain become the protagonist. In the end, I couldn't figure out which link went wrong, and the male protagonist actually found out about it.
