I think PJ and Prang make the better looking couple but that may be my PJ bias speaking. Prang also suits that look, old fashioned all around Thai woman.
Bella sounds excited to play an all out evil chick. I hope she could pull it off. There was that one shot of her in the clips, where she's sitting down with the fan that looked promising cause her eyes went all cold and evil like. And once the body switch happens, I hope her goofiness and mischievousness is more goofy and playful and not retarded like Pancake in Tawee Pope.
I hope Pope could pull off the arrogance too but I can't picture it at this point.
