Jon is a simple, honest young man. After graduating, he struggles to find a job and eventually decides to become a taxi driver. On his first day, he gets into a heated argument with Dr. Manop after the doctor cuts him off in traffic. During the confrontation, Jon meets Nannaphat, the doctor’s kind-hearted girlfriend, and falls for her instantly.
Later, Jon rescues Nannaphat from an attempted sexual assault and helps her escape the chaos caused by Chitchanok, who crashed Nannaphat's engagement ceremony to Dr. Manop. Heartbroken, Nannaphat decides to leave the turmoil behind and work at Sia Mangkorn’s casino, replacing Kimheng, the boss's wife, who claims to be pregnant. Unbeknownst to her, Kimheng is faking the pregnancy as part of a scheme to eliminate Nannaphat and seize the family fortune.
While Jon is dropping Nannaphat off at the casino, Aor—a young woman hired as a surrogate for Kimheng—changes her mind about giving up the baby. Aor sneaks into the back of Jon's taxi to escape, with the henchman Songyot in hot pursuit. Suddenly, Aor goes into labor. Jon delivers the baby in the car and flees with the infant. From that moment on, Jon becomes a "father with a tag-along child" by default, adopting the alias Lorsu.
Seeking his child, Sia Mangkorn orders his men to hunt them down. To frame Jon, they create the persona of a "Hitman Father" to commit robberies, hoping the police will do their dirty work for them. Meanwhile, Nannaphat moves on to manage an elephant camp. Jon crosses paths with her again when he saves her from a rampaging elephant, but she doesn't recognize him behind his thick beard. Working closely together as "Lorsu," the two begin to develop feelings, though Nannaphat remains guarded due to her past heartbreak.
Eventually, Aor recognizes Jon and demands to see her child. Softening, Jon takes her to see Nong Woon (the baby), unaware that Songyot’s men are tailing them. Jon decides to return Nong Woon to Sia Mangkorn and reveals his true identity. Feeling betrayed, Nannaphat kicks him out of the elephant camp. However, Sia Mangkorn allows Jon to stay at his house to help care for the child. Growing fond of the baby, the Sia considers retiring from his illegal businesses.
The plot thickens when Kimheng reveals she is actually a spy sent by Sia Nin to gather intelligence. Jon saves Sia Mangkorn from assassins sent by Sia Nin, but Songyot has another plan: he lures Dr. Manop into a gambling addiction and uses him to kidnap Nong Woon for ransom, once again framing Jon.
Will Songyot’s evil plan succeed? Can Jon clear his name of the hitman allegations? And how will this love story between two people of such different backgrounds finally end?
