Wiman Sai

Panin and Arisara meet in Rayong province when Arisara helps him after he was attacked by thieves. She mistakes him for a foreman at a construction site and gives him money as he had lost his wallet. Without knowing each other's identities, they both fall in love. Panin is impressed by her generosity, and for once he finds a girl that likes him for himself, not for his money or status. Arisara is impressed by his integrity.
When they return to Bangkok, Arisara discovers that Panin misled her about his true status and Panin discovers that she is the love interest of his younger brother Yoh; so both are angry. Arisara is upset that Panin doesn't dare reveal the truth to his brother: that they have met before and that they like each other. Panin is upset because he believes she trivialized his love, that she was just flirting with him, leading him on as she did his brother and just like she openly flirts with her friend Non.
Their misunderstandings are compounded by Yoh's obsessive love for Arisara as Panin struggles with the notion of giving her up to his younger brother.
