I watched the first 2 parts of the first episode (with English subs already) and I find the plot really unusual for a GMMTV drama. I think the treatment will be a recurrence of flashbacks and flash forwards.
Plus the aesthetics of the scenes give this the indie film-like feel.
I'm 38m in, and it's just too boring. I tried to give the whole episode a chance. Really nice cast and storyline, but the execution needs more improvement. The storyline is usually something from Japan that I really like and would watch, i.e. "Flavors of Youth". Maybe because it's 3 storylines going on at the same time. It's like you're trying to get into the current one, and then the next one comes in before you can.
