Waan Jai Yai Tang Dao

Tom, a talent manager at a famous Luk Thung (Thai country music) label, discovers that his superstar girlfriend, Dujdao, is having a secret affair with Sin, the company’s young vice executive. During a heated argument, a furious Dujdao speeds off in her car and accidentally strikes V4 with full force. Panicked, Dujdao flees the scene, leaving Tom to take the fall.
Unbeknownst to them, V4 is actually an alien sent to Earth on a reconnaissance mission. Tom brings the injured V4 to his home, where he lives with Ta Chuen, a devout Buddhist; Taem, his tomboyish high school sister; and Tum, his mischievous younger brother. None of them believe V4’s claims of being an extra-terrestrial, assuming instead that the accident has left her mentally confused.
To protect her identity, Tom tells everyone she is a new maid from the countryside. This sparks intense jealousy in Ratchanee, a local teacher who is in love with Tom. After discovering V4's true alien nature, Ratchanee teams up with Ajarn Sonthaya, an ambitious science teacher who wants to use V4 as a lab rat for his experiments.
To keep her safe, Tom finds V4 a job at his music label, owned by the lecherous Sia Samroeng. While the boss constantly tries to corner her, V4 is protected by Tom’s best friends, Pong and Lisa. Against all odds, V4 rises from a cleaning lady to a back-up dancer, eventually becoming a miracle breakout singer. Her rising fame and charm fuel Dujdao’s envy, leading the star to sabotage V4 at every turn.
As Tom steps up to shield V4 from these threats, the two begin to fall in love. However, their romance faces its ultimate test when V4 receives a signal from her home planet: her people are coming to take her back very soon.
