At Tokyo's high-class club, "Chateau du Amour," Renjouji Kiriya holds the esteemed title of the number one ranked host. The club specializes in catering to female clients with the company of cultured and charming men. However, unbeknownst to many, Kiriya is actually Yamada Kotarou, a boy who came to Tokyo from Nagasaki to settle his parent's debt.
Despite his popularity, some of the other hosts are envious of Kiriya and are determined to dig up any dirt to discredit him. This proves challenging for Kiriya, especially after a former customer abandons a young, adorable girl claiming he is the father. As if that wasn't enough, his Nagasaki girlfriend, Miharu, arrives in Tokyo with no knowledge of his profession.
Additionally, the story includes a one-shot titled "Apple."
