This pretty much caters to all you perverts out there, myself included. You don't even need to get to chapter 200 of kimi no iru machi to enjoy these amazing chapters. Feel free to read them once you get to like chapter 144. Basically, this these chapters take an alternate route in each one, where Haruto, the main protagonist, goes out with almost all of the main girls in the manga. Not just goes out either...Let me just say these chapters should be considered hentai. Perfect.
