Produced by GMMTV, the series stars First Kanaphan, Khaotung Thanawat, Joong Archen, and Dunk Natachai. In short, it’s a love story between an undercover cop and a killer.
Kant (played by First) is a tattoo artist with a criminal past as a car thief. Due to his record, he’s blackmailed by the police into going undercover. His mission: infiltrate and investigate a pair of assassin brothers—Fadel (played by Joong) and Baison (played by Khaotung). To get close to them, Kant targets the younger brother, Baison. However, Fadel is extremely cautious and doesn’t let strangers near his brother. So Kant enlists the help of his friend Style (played by Dunk) to flirt with Fadel and distract him, giving Kant the chance to approach Baison more easily.
The two friends work in tandem—seducing their targets while secretly collecting evidence for the police. Eventually, they manage to gather proof that the brothers are indeed killers. But during the process, they fall in love with the very people they were supposed to betray—the very ones they were sent to bring to justice.
Regret sets in, and the emotional conflict begins. The undercover pair try to protect their lovers and help them escape the consequences. All four become entangled in a web of deception, loyalty, and love—a story that begins with lies but spirals into something far more complicated.
Starting from episode 2, the series features steamy bed scenes (super intense!!!). Each couple’s relationship develops at a different pace. Personally, I prefer the pairing of Fadel and Style—one is obviously (and adorably) trying to seduce the other, while the other knows he should resist, but can’t help falling deeper. The slow-burn tension and emotional push-pull make it incredibly compelling.
Another standout is Baison, essentially a love-struck, unhinged killer. After falling for Kant, he wants to be with him all the time and is even willing to leave the assassin life behind. But when he discovers Kant’s betrayal, he snaps—turning vengeful and dangerously unstable. That love-and-hate dynamic brings huge emotional intensity to the story.
