สุภาพบุรุษลูกผู้ชาย

This story is of a young man named Rung who grew up as a poor orphan. He is diligent and hard-working, doing everything he can to not only care for himself, but also to save money for eye surgery for Pinky, a blind girl whom he considers his sister. Whether or not they are well-off, or whether he is living in a cramped house or in the slums, he still maintains a positive attitude. Meanwhile, Rung crosses paths with the young and rich Praewa. Praewa is beautiful, a bit spoiled, but kind-hearted as well. When Praewa gets to know Rung, she tries to enlist his help in her family business. When many obstacles, including their past and social status come in their way, will their determination and love be enough to get them through?
