Both are slap-kiss lakhorns!
Both ML´s are hot-tempered alpha-heroes that sometimes borders on being Anti-heroes.

Both lakhorns basically delivers a journey of how main-leads come to meet, bicker, hate each other, get to know each other, fight...save each other...and fall in love during all of it.
Leh Ratree is obviously more of a domestic drama while in Ploy Lom Phet the leads were always on the run and getting chased.
