Fah Hin Din Sai.

Din is a good-natured orphan boy raised in a Buddhist temple. Apichat, a businessman, likes Din’s character and invites him to work at his company with Sai, Din’s female friend. Apichat wants to give his son and daughter, Akanee and Fahsai, life lessons, so he assigns a new project to four of them to invent a new lot of furniture promising a rocket sale. Fahsai starts to fall for Din during the challenge.
