No not substitute wife - Mia Teng is the wife that is legally marry with marriage license. The story is about praeke is a playboy who has a girlfriend that his mom doesn't think that she can be good wife or a fit mother in the future if he marry her. She can only be someone mistress. That girl's name is Promchut. So his mother knows nangeke's family from childhood when both fathers were still alived they were friends so she wants her son to marry with nangeke- Arunpapai is her name. She is a propers and well trains. After praeke's mom meets Arunpapai, she wants her to be her daughter in law. Arunpapai has a boyfriend who is a palut( an officer or something) but one of the girl likes him and she accuses him that she is carrying his child so nangeke is embarrasses by this matter so she decides to marry the praeke. It a good lakorn but with Ning version it was a little too slow and nangeke is a little weak. I think Araya can pulls as submissive wife. It 2011 She doesn't have to be weak. They can let her be a smart working woman to steps up nangrai Promchut.what's the story line.. go did someone already asked.. lol..i guess i'll read the other post..but i love rome and araya. can't wait.. what does the title say anyway.. i can't seem to understand TENG..lol.. does it mean something like substitute wife or something..
