Flash Marriage Episode 16

The gang thinks Nu is the mole working for Manun because he is trying to find Lalin. Manun's plan to destroy Warong's company hinges on Nat signing the contract in Singapore. He tells Tul that he doesn't have to worry about being caught as his mole because he has set up Nu to be caught in his place. The only problem is that Nat has decided not to sign the contract. Nat tries to leave the country without her husband, but a panicked Tul, who sees all of his plans being ruined, tries to force her into signing the contract. Fearful that Tul will catch up with her, Nat recalls a few suspect moments that might indicate that Tul is dangerous. Warong goes back to the office so that everyone can see him alive. Phrao wakes up and tells Nat that Tul is Manun's son. (Source: Dee at MyDramaList)
