Girl! I promise you this is the exact drama. Hmm... it has the evil mother, evil girlfriend trying tear their faith apart. You better get that drama your currently watching out of your anal 'cause this is lit as fuck my weebs.
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.
Similar concept of interchange of identities of a poor and a rich girl.
They both have girls switched at birth. One was raised in a wealthy family well the other was raised in a poor family.
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.
