Pojaman is sent to live in Ban Sai Thong upon her deceased father's wishes. There she instantly feels unwelcomed by its residence, her second cousins the Sawangwongs. Her aunt Phanarai and her youngest daughter Ying Lek hate Pojaman, while the eldest daughter Ying Yai is cold to her. However, she immediately bonds with the youngest son Chai Noi, who is crippled and his nanny. There at the Ban Sai Thong, Pojaman is not looked upon as a relative and is ordered to work like a servant. She is sad and homesick but bears the treatment because it is her father's wishes that she finishes her education.
One day while wondering around the grounds of Ban Sai Thong, Pojaman is frightened by an elderly servant, whom she thinks is a ghost. While running for her life, she trips and is caught by Chai Klang. His nick name "Chai Klang" means middle man/guy in Thai referring to the fact that he is the middle brother. Although Chai Klang is a stern person who doesn't show many emotions, he immediately empathizes for Pojaman and fights to get her the respect worthy of a relative. He makes himself her guardian and seeks to teach her qualities of perseverance and patience. Though it's not in the will, he also knows that Ban Sai Thong belongs to Pojaman's family after his grandfather dies.
Because of the care and attention Chai Klang gives to Pojaman, his mom and Ying Lek grow to hate her even more. Naturally, their guardian/child and brother/sister relationship grows into love. They get married, but Pojaman is not certain that Chai Klang married her for love because he never told her he loves her. So how will Pojaman and Chai Klang overcome their obstacle of having his mom and sister accept her as his wife and did Chai Klang marry her because of love or was it because of Ban Sai Thong?
