Nabi, My Stepdarling.

Pichet is married to Waree and has a son, Kawin. Sirin manages Pichet's DUBAI CLUB. Pichet loves and trusts Sirin so much that Waree thinks she's Pichet's mistress. Waree’s sister, Weeranat, planted this falsehood in Waree’s mind when she herself fell in love with Pichet. With each day, Weeranat becomes more paranoid. Soon thereafter, Waree is found dead and Sirin has disappeared without a trace.
