She is beautiful without glasses, but man do they give her that gap moe.
This manga really gets that nostalgic feeling that the guy was talking about. I searched the Kowloon and the pictures are impressive in many ways, it was decrepit but it had a presence it was like a city of legos stacked on top of each other, but if the wiki is something to go by it didn't seem a good place to live.
