I think both twins are doing fantastic on their roles! Pon is so adorable and sweet with wat and pen is hot and sassy with thrie!
And also I actually think it was a good idea that they had the pon's character be played really weak rather than just somewhat weak bc it set up for a very high satisfactory motive for the viewers when payback came around. If pon's character hadn't been played weak enough, then the bad people's mistreatment of her would have just felt blah and over the top....in my opinion.
I also think the pa and nat characters are hilarious..."nat's" acting (his real name slips my mind) is especially good in here. Hope he gets more lakorns. Lol
