"What are you, a weirdo!?" Hiroki would do just about anything to get Izumi-san's attention! He's cute, innocent, and a harmless looking guy, but he always has mischievous plans to be with Izumi-san. He also makes a spare key to Izumi-san's room and steals his underwear! A little hentai-esque?! But there's something about him that makes you love him even more.
