Rak Leh Saneh Luang

Phuwit and Piwat are brothers with the same father but different mothers. Though they look like each other as twins, their personalities are very different. Phuwit has been raised by Pao, his uncle in the farm, so his personality is rough, hot-tempered and outspoken while Piwat has been raised as a polite gentleman in Bangkok.
Piwat's parents engage Jarulin to marry Piwat because they want her family to help their bankrupting business. However, Piwat can't marry with Jarulin because he gets in an accident and becomes blind, so he and his family ask Phuwit to marry with Jarulin instead, and Piwat goes to stay at Phuwit's farm.
