Kaew Lorm Petch (2008)

Same swapped at birth story and the real daughter of the rich people end up living at their house due to a circumstance. Poor woman's daughter makes the rich woman's daughter's life a nightmare.

Both have similar plots since Kaew Lom Petch is a remake of Luerd Hong.

In both stories a woman switch babies,although for different reasons.

The Male lead has a brother in KLP who is a playboy,similar character exists in LH only he is the female leads biological brother (although they don`t know it) this time.So FL actually has 2 biological brothers in LH.

The main leads do have more encounters in KLP.

These two dramas are nearly identical at times, but I feel that Kaew Lorm Petch is the better version, although it's tone darker and has a much more satisfying ending.

Sakul Ga is similar to Kaew Lorm Petch :
-Same grandmother
-Poor female lead becomes a rich heir and knows her true identity

Both are family oriented dramas.

Much over the top-ness, where there is this sweet and nice Nangek..and a evil selfish Nang Rai who does Everything to destroy her.
