Parakit Pichit Dok Fah(2006)

Original title: ภารกิจ พิชิตดอกฟ้า

A small-town boxing champ determined to better his village heads to Bangkok for university, where he falls for a police general’s daughter, befriends a hidden prince, and gets swept into a wild fight against powerful criminals—all while trying to prove that love, courage, and goodness can change both hearts and society.
