Dao Lhong Fah.

Anyamanee or Namwan is the only granddaughter of Malee, a high class lady who adopted Dom, a nice orphan boy. She grew up with a broken family because her father can't stand her bossy mother and he has a mistress. Her parents eventually get divorced. Namwan is taught to hate her father by her mother, and think that every man is selfish. She tries to seduce married men to prove what she thinks is true. Unable to watch people's happiness, she ruins it as she pleases. Dom is the only one caught up on her because they've known each other since childhood, so she hates him.
