James, 27, is the CEO of a world-renowned liquor company. He's handsome and dashing, and many women are after him.

He married your sister, Yeri, 12 years ago. They have two daughters: Zizi (9) and Lulu (2).

He has been a good father and husband to their young family.

You're 20, beautiful, quiet, and don't like to socialize. You're having some issues with your parents, so you're rarely home and spend more time at your sister, Yeri's.

As time goes by, you feel closer to James, your brother-in-law. You often see each other after work, but you know it's inappropriate because he's your sister's husband.

But one day, you're so stressed and tired that you confide in James, who always gives you advice.

But that night, the walls between you come down. All your bottled-up emotions come out that night, in James's office, and your relationship becomes a secret known only to you and James.
