Overview
A poor Chinese family, the Song family that lived in Yaowarat gave up their youngest son Chai to a family friend, who wasn't able to conceive and they wanted a child to run their family business. The Song family later was faced with many problems. Their oldest son Ah-Yong died and the father got hit by a car and passed away. The mother was pregnant at the time. 17 years pass and Chai has grown up to be very irresponsible. His adopted father gets angry at him for messing up a very important meeting and Chai overhears the truth about his adoption, planning to go to Thailand to find his birth parents.
