It's alright. I would have prefered a better ending, or at least an epilogue of some sorts. I personally don't like stories that only have the red light district, so I was already biased against it from the first place. The fact that the two main characters didn't even do anything in the sense of forming an actual relationship i.e. bf-gf/fiance-fiancee/husband-wife/etc sort of left a bad taste in my mouth. The ending is too vague for my taste.
6.8/10 - Art was good enough, the story was good enough for what it was, however, the ending is essentially non-existent the way I see it, but it did get points for not being a completely open ending like other mangas.
