Somewhere Our Love Begins.

Panin and Arisara meet, in Hau Hin, when she helps him after he was attacked by thieves. She mistakes him for a hotel driver and gives him money, as he lost his wallet. Without knowing each other's true identities, they both fall in love. Panin is impressed by her generosity, and for once he found a girl that likes him for himself, not for his money or status. She is impressed by his integrity. Upon returning to Bangkok, Panin continues to mislead Arisara about his true identity. Later, when Panin discovers that Arisara is the classmate and woman his younger brother Yoh has been in love with through college, he blames her for his brother's near-drowning. Though conflicted, he still seeks revenge.
