After Being Forced to Play the Sycophantic Villain to the End

After being forced to play the lovesick villain, Xie Cheng wanted to part on good terms. But then the male lead stopped following the script.

PS:

Contains unorthodox righteous male leads, including humiliation-chasing, resentful-wife, and married-woman tropes, as well as the male lead's POV and plenty of intense rivalries.

Theme: Devote oneself to the Dao.
