The Sister's Ruse 01

The female protagonist was nearly ten months pregnant when her half-sister, with whom she had no blood relation, came to seek refuge with her. Unexpectedly, the half-sister tried to seduce her husband. Because the protagonist was pregnant, her husband was susceptible and quickly got involved with the half-sister. After they got together, the half-sister conspired to murder the protagonist. However, the protagonist was rescued by her brother, who also arranged for her to have plastic surgery to change her appearance. She then re-entered the lives of her ex-husband and half-sister to begin her revenge. In the end, she left her ex-husband with nothing, made her half-sister regret her actions, and ensured that all the villains received their just desserts.
