The attraction and seduction part between two persons are totally understandable.
However, some reviews on Wiki make it seems more like a sin on the legal issue part, because she is counted as a child. When I checked this book from the library, it's under the category of crime, sin, and also love story. And even when I want to use the title 'Lolita' on the blog, it doesn't allow me to publish it, so I changed it to 'haha'.
