When Kai hears that his next door neighbor, Chris, will be staying with him while her parents are overseas, he thinks nothing of it. They're best friends, after all, and have been since childhood. Sleepovers are hardly anything new. But what Kai doesn't immediately realize is that he and Chris aren't children anymore. They're both 18 year old heterosexuals, neither one of whom has ever been in a romantic relationship, and their feelings towards one another are no longer as simple as they once were. This event could very well push one of them over the edge, changing their relationship forever. Updated: May 12, 2017 Developer/Publisher: Zetsubou Games Censorship: No - 18+ Adult Patch Pre-Applied
