When I saw the trailer back then, I thought, wow I have to see this. In the end, as is often the case, the series didn't deliver what the trailer promised.
Don't get me wrong, all in all it wasn't bad, but there were too many inconsistencies. And the ending? Well, I didn't get it.... it just stops abruptly. I hate it when there is no happy ending, even though the characters have already suffered in the beginning. I think a happy ending makes more sense here. Or maybe it's just me being too romantic, I don't know.
A second season would have to round off the story, especially because Ken travels to Bangkok again in the last scene. Unless I have misunderstood something. The ending is really a bit confusing for me...
The main couple didn't convince me, unfortunately. They looked so good together, but somehow the spark did not jump over. I liked the general story, but it was only halfway satisfying.
