Overview:

Bpeeyachat, a young orphan, befriends Monthai, a wealthy boy, during her childhood. After a car accident takes her grandmother, her last family member, she moves in with Viyada's family. Monthai leaves for studies abroad due to family issues and sends many letters to his fiancée, Viyada, but they are answered by Bpeeyachat instead, as Viyada is more interested in meeting other men. Monthai's mother becomes ill and requests Viyada to care for her, but Viyada declines, so Bpeeyachat goes in her place. When Monthai returns, he mistakes Bpeeyachat for a gold-digger pretending to be Viyada and treats her poorly. Over time, he starts to care for her, but trouble arises when Viyada unexpectedly shows up.
