Doutei Tora to Tsundere Usagi

Welcome to "Moon," an underground dreamworld (read: host club) for rich men to enjoy alcohol, sex, and anonymity. Workers of moon, aka bunnies, aren't allowed to ask about their customers' private life, but there are no rules against knowing each others'. Bunnies all have their reasons and motivations for staying and working, and just like that, moon is home to an interesting mix of characters, stories, and... relationships?
