Neung Nai Suang (2005)

remake at a different time period and different actors but the same story....................................................................

Nueng Nai Suang is similar to La Ong Dao because :
-Hate to love story
-ML had a bad picture of child obese FL
-ML falls in love with current beautiful FL

Both are set around the same era.

In both the female lead is strong-minded, beautiful, well mannered and easy to fall in love to. But of course only the male lead started of by not liking her even hating her - always misunderstanding her and not able to see the true her. As feelings start to grow he keeps getting jealous seing her involved with other men.

You will get the same feeling as in both dramas the male character keeps misunderstanding the female's pure heart. So while he himself doesn't realize his own feelings, he keeps teasing and hurting her.
There is also this mean second female in both dramas
