Wong Wien Hua Jai (2009)

Both are forced marriage lakorns due to some misunderstanding. FL ends up working on ML's farm in both. Both dramas land under the slap/kiss genre, but Jao Sao Jamloei has a softer take on the slap/kiss genre. Both have ridiculous drama scenarios that are pretty laugh out loud worthy.

In Wong Wien Hua Jai similar pregnancy event which lead to a marriage.
Hoewever, The differences in this is in Wong Wien Hua Jai the Male lead married the brother-in -law's ex girlfriend for his sister sake. While in Paen Rai Long Tai Wa Rak, the uncle married the female lead for the niece's sake.

Jam Loey Rak also deals with kidnapping, but the story seems more soft than Wong Wien hua Jai, there are two versions for this but I watched the last one which is from 2008.

Both stories talks about revenge and also kidnapping, Wong Wien Hua Jai is more dark because it has more violence than Game Payabaht, and Game Payabath the main leader wants to revenge for the death of his sister by kidnapping and torturing the sister of his rival. The story is not that soft but also not that dark.
