To me I think the story is revealing itself pretty well and the back story is progressing nicely, if we jumped to them knowing the truth already in just 2 episodes then there is no more story to tell for the rest of the episodes, and we'll have nothing in between beside side shows/characters.
With just 2 episodes we already knows reason why Sia is hating on Krating, and why Krating is being the way he is. Both our pranang has a tormented history and their enemy is one and the same, but their lives and their loses interwinded so badly that it will take both of them together to find themselves again. I like the pace its going so far, I like how their characters is building up nicely. I'd hate to see them meets and suddenly come to an understanding or knowingly so soon... then what's next, beside a flat melodramatic same old storyline.
Cherry and Ken is both a great actor/actress, so why not uses their talents to the fullest instead of those cheesy love storylines where they did nothing beside staring at each others for fan-serving like the craze koo-jin. I believe their talents/levels and their story in Krating is beyond that fantasy. So I'd enjoy Krating for what it is, and not for the cheesy love story that some peoples come to expect from lakorn these days.
