Well, it's hard to say because both Ken and Ann have a solid fanbase. I believe, JLR Ken and Ann's version would be popular among the fanclubs but definitely wouldn't have captivated the entire nation alongside overseas. There's just something about Aum and Aff together that generates so much chemistry, anticipation, and perfection. I adore Ken and Ann as well but Aum and Aff have something quite unique and different from the others that it's "chai leur," in other words, "That's the one!" I'm not even sure if I will follow up on Sawan Bieng let alone JLR if they did remake it.
Plus, it is true, Ann has been acting for a while now, she's done a whole collection of roles. It would be awkward to see her as Soriya as it is in Sawan Bieng and I know that Ann is a great actress but there's only so many amount of times you can play the sweet and innocent role before it becomes redundant.
And another thing, Aum and Aff have been underestimated for so long, for them to surface and portray such challenging roles and succeed, winning the hearts of everyone, that is tremendously astounding. It's about time both are recognized especially Aum as he's such a great actor. I already thought that Aum was great in Rai Rissaya but I never finished it until recently due to the odd pairing of Aum and Cherry. Aum can portray any character so well that's probably why everyone was surprised when he transitioned from a proper guy into a sadist like Harit. That just shows what a pro Aum is in acting.
I love this pair, Aum and Aff. They're awesome, beyond words, like they complete each other onscreen. So I really could care less about their private matters but please, just keep producing lakorns together for us.
