Keng is a young and pretty young girl who’s often mistaken for a boy because she’s a bit of a tomboy. She meets Yokhin, a popular and handsome author. Yokhin quickly takes a liking to Keng because she’s obviously hardworking, honest and brave; she works very hard to take care of her sick mother, her grandmother and her indebted father but never gets out from the right path.

Kring Khlong Takian could move too fast for the naked eye and disguise himself as others.
