The similitudes in these shows is that they revolve around cheating. Otherwise, while Plerng Boon has much more production value (quality of the show, acting, screenplay...) as a Ch3 product and the story is more "complex" Talay Prae is of a lesser quality overall. Another difference is that the motivation of of the cheating partner and their characterization are world apart.
