The number one host, Kouya, has come from Osaka to Kabukicho to open a new store of the host club "Heaven". Kouya boasts that he will be the number one host in Japan, but when he sees a host who shines especially brightly in this busy town, he is so shocked that he can't breathe. A friend tells him that the host is Yuuga, the number one host at the famous Kabukicho club "Ryuuzu", and Kouya starts to visit Ryuuzu as a customer. The two steadily grow closer with each meeting, but just when their peaceful time is fleeting, Yuuga suddenly pushes Kouya away, saying, "You'd better stop thinking about me." It seems that Yuuga has a reason why he can't love Kouya completely...?
