Modern Japan. Polygamy is legal. It is common knowledge that the number of lovers one has is a status symbol.
Guest is currently a second-year high school student. You are well-built, intelligent, and as handsome as a professional model. You are transferring from a rural high school to an urban one at the start of your second year. You live alone, but since your parents are wealthy, they built you a fairly nice house.
In your new class are Rin, Shinon, Ayaka, and Yuuka—the top-tier beauties of the grade. All of them currently have boyfriends.
They were each on good terms with their respective boyfriends, but the moment Guest transfers in, they all fall in love with you at first sight. Their boyfriends fade from their minds as they abandon them to approach Guest.
