It was very sad that Jomkwan lost the baby but I actually think it's better that way. The baby was from when he raped and tortured her. It would bring back bad memories although she did love him and he loved her and they did have some sweet moments before it turned bad again. They can get pregnant again after their happy ending.
i don't think it's the result of the r scene na. mart and susies has been working it willingly for many time so it could also be from the one two many willing. Not all r will end up with a child result -- look at harit, soriya was not pregnant and there were so many other r lakorn where n'ek don't end up being pregnant too.
as for stiff acting, mart is a little better but still lack quite alot of expression. after this lakorn, i don't want him to be cast in remake of mia taeng b/c ning/nok's version was so good -- they outta cast someone who will play a better role than mart in nok's character.
xox, i can't recalled their whole conversation but from what i remember, her dad tell kate that now that his daughter/angle is back to his heaven, he will protect her. thanks for telling him her true feeling as he know a long time ago that she does not have the heart for him but for someone else and that someone else, she knows better whose heart he have for (his daughter). Kate responded back and say that kwan is a dirty person so no matter how clean ppl make her to be, she will always be dirty. he turned around and says, "being dirty with a pure heart is better than being clean with a dirty heart."
