Jone Plon Jai (2003)

The Wongsaworarat family has two sons, Phuriphat and Peeraphon. Their mother, Khunying Kamala, favors Peeraphon, prompting their father to send Phuriphat abroad to study. Peeraphon falls for Mathumas, a beautiful hotel public relations officer, despite his mother’s plans for him to marry Chalita, the daughter of her friend. After years abroad, Phuriphat returns to Thailand and rescues a young woman from a robbery, only for her to mistake him for the attacker and flee after kicking him. When his mother orders him to separate Peeraphon and Mathumas, Phuriphat agrees and soon discovers that Mathumas is the very woman who assaulted him. He then sends his subordinate to follow her and pressure her to stay away from his brother.
