Flash Marriage Episode 17

Tul catches up with Nat and begs her to forgive him, so she pretends to do so. Nu lets Tat follow him so that they can trap Pong and Lalin. Suspecting that Nat was informed by Yut before they shot him, Manun orders his son to drive her to a designated spot to kill her. As Nu packs his belongings to leave the country, Phrao's mother walks in with a butcher knife to avenge her daughter. Nu pushes her away, saying he's not the mole that tried to kill Phrao. She chases him, asking who he is. Lalin walks in and demands to know the truth. Just as he's about to slap Lalin, he spots Pong at the entrance. Finally cornered, he tells them everything he knows about Tul and Manun's plans. At the same time, Warong finds out that it was Tul all along and informs the family. Just as Tul is about to kill his wife, Lalin shows up to save her. A battle ensues, and the bad guys are dealt with. Job is complete, and Pong decides to walk away from the fake marriage.
