Pin A Nong (The Perfect Stranger)

Pin Anong (Peechaya Wattanamontree) is forced to repay her debt of gratitude to Krongsuk (Apiradee Phawaphutanon) by marrying Khun Yai (Sukollawat Kanarot), Krongsuk's rough and ruthless stepson, who is also the true owner of the dairy farm that Krongsuk wants to seize. Khun Yai pretends to be cruel to Pin Anong, even though he loves her deeply, because he is unsure if she conspired with Krongsuk to murder his father in order to take over the fortune.
Khun Yai secretly searches for evidence to expose Krongsuk's crimes while simultaneously testing Pin Anong's true intentions. Eventually, he discovers that Pin Anong had no involvement whatsoever. In the end, Krongsuk faces the consequences of her wicked deeds, while Pin Anong accepts Khun Yai's love, ready to stay by his side and take care of him forever.
