After Dressing up as a Vicious Female Supporting Character, She Had Sex with the Heroine's Sister.

Mu Yao passed through the book and became the vicious female supporting character in an ancient bloody novel. The original protagonist was a wealthy daughter, but she forcibly separated the male and female protagonists, and ended up with everyone betraying their relatives. Fortunately, when we traveled back in time, both the male and female protagonists were still in their teens. Before the plot even started, Mu Yao decisively chose to stay away from the male and female protagonists and avoid the plot. He only hoped that after the male and female protagonists fell in love with each other, they could forget about themselves as the supporting female characters.

In desperation, Mu Yao had no choice but to be a tool person who worked hard to promote the plot.

Later, after learning that the little boy was the biological sister of the heroine, Mu Yao felt compassion.
