This manhwa contained a lot of 'deep thoughts' which I think was perfect for the subject matters it was dealing with (youth, loss of innocence, violence, growing up, love, etc...). Sometimes these got a little too heavy and I skipped some of the text, but when (most of the time) I did read them I found the ideas the words contained very beautiful and thought-provoking (which also worked with the amazing art).
I think maybe because this manhwa is about growing up, especially with the deep ideas, it will appeal to teenagers/young adults more than 'grown-up's' but I think its well worth a read for someone looking for a good read with a memorable relationship.
On another note there is a lot of violence, which originally appealed for me because I liked the slightly sado-masochistic relationship that was prevalent between Jaehee and Dai for the first half of the series. However for those who dislike that sort of thing, there was very little/none of that in the second half, and once you get past the first couple of chapters the deep love between the two is very clear. Their complex, deep relationship was what kept me hooked on this.
In regards to the rest of the violence throught the volumes there was a lot. Although the violence was never romanticised, sometimes it was taken relatively lightly (the end however disputes this somewhat).
Despite preferring yaoi to shounen-ai, I absolutely loved it and found it very beautiful. What was most notable for me was that although Dai was clearly the stronger there was never (and I mean it) any sense that this couple was not equal. I loved their relationship, their closeness, their complexity, and though there was no sex I had no complaints (this is coming from a hardcore yaoi fan!)
The art, which I originally found mediocre, grew on me. I particularly loved the way the mangaka drew Dai, as well as some of the deeper scenes.
The ending I disliked. Maybe because the site I was reading it at mixed the pages up, but it seemed too rushed and slightly inconclusive. But maybe disliked is too strong a word, because despite that, I think it reflected faithfully and stayed true to the flavour of the series.
Loved, loved, loved.
