The only reason I docked 1 point for the story is because sometime it felt rushed. Some elements were mentioned once and then never brought up, and the ending, while 100% satisfying, felt rushed and a bit predictable.
That said, everything else about the series is perfect. The characters are awesome, the art style is beautiful, and whle I wish the story had more than 35 chapters, it doesn't overstay it's welcome. Unlike another Manhwa I read, ''My Cotton Candy'' the story doesn't continue after the expected ending (Cotton Candy did it, and completely ruined the ending)
as of whn I write this, this was, by far, my favourite Manhwa.
