Saeb Salab Kua (Swapping Bad Boys):
This is the story of two polar opposite young men: Pla-yai (Thanwa Suriyajak), a meticulous and strict young businessman, and Sian (Thasit Sinkanawiwat), a cheeky and playful motorcycle taxi driver. Due to an accident, their souls miraculously swap into each other's bodies, and utter chaos ensues.
Sian is initially thrilled with the wealth and luxury while living in Pla-yai's body, but he soon realizes that a millionaire's life isn't as happy as he thought. He constantly has to watch his back against greedy relatives who are eyeing the family fortune. The only thing that brings Sian happiness is being able to get close to Namphet (Thikamporn Ritta-apinan), Pla-yai's secretary, whom Sian has secretly been in love with for a long time. Namphet is surprised by her boss's sudden change in personality, but she finds herself liking this new version of him.
On the other hand, Pla-yai, now stuck in Sian's body, desperately tries to find a way back into his own body. He receives help from Saipin (Anyarin Terathananpat), the sweet girl next door who has always been in love with Sian. Pla-yai becomes deeply impressed by her cuteness and good nature, while Saipin secretly finds herself admiring this "new," more refined version of Sian.
When the four of them discover that the incident was not a mere accident at all, they team up to hatch a plan and successfully catch the culprits behind it. In the process, they also manage to return the two young men to their original bodies. With the chaotic ordeal finally over, the two men rush to sort out their matters of the heart, ultimately winning the girls over and securing their true love.
