Bella should be someone who is luekrung, Toon I believed Rita is a good choice for Bella. She looks so plain yet so hot at the same time. As for Edward, Chakrit wouldn't fit the role. And it really depends on how you read his character and used it in your imagination. How I imagine him when I first read the book, he has this fair snow color skin. He feels cold but when he cuddles you, it feels so warm. He has that savage look but yet so charming. Aum would be a better pick for me since he is known as the red-lip pra'ek. Ken... as much as I love this dude, he makes a hot vampire but not Edward. Funny how I can't think of any pra'ek from Ch7 that would fit the role.
My story. Umm... I still need to think that over but here is a glimpse if it was a lakorn. Rita (Bella) lives with her mother(a luekrung, a freelance artist residing in Northern California) Instead of having her mother with another man, she dies. Her father (also a luekrung, a former General from England currently living in Thailand) was sent a letter informing him to take care of Bella until she finishes college. Oh yeah I prefer for them to be a little bit older- instead of high school students they're college students. She meets Aum (Edward) at the International Academy and I can't think any further. Be back to add more to my plot.
