For Richer or Poorer; The Billionaire's forbidden vow

Ethan is a Billionaire who needs to get married in order to inherit a fortune from his eccentric uncle. His uncle's will stipulates that Ethan must be married within six months, or he'll lose the fortune. But Ethan doesn't want to be married, and he has no interest in a woman who's only after his money.

One day, he meets a struggling artist named Sophia who's trying to make ends meet by working odd jobs.

Ethan is struck by Sophia's beauty and her artistic talent, but he's also impressed by her down-to-earth attitude and the fact that she doesn't know who he is or that he's a billionaire.
