Maybe it is one of those things that is only poisonous at really high doses or concentrations? Like nutmeg for exampleI'm guesstimating that this one will end up being 12 episodes because the development of this one is steady. Not too draggy but its not fast paced either. I think Mae Kong is getting more and more crazy so I also believe that she is definitely trying to poison Thun Chai. At the same time, I'm like how does one just simply get poisonous medicine so easily like that and why does that guy who sells it not suspect anything? lol .
