Papaya Gundan★

Club Papaya is run by Hajime. Like most hostess clubs, the girls who work for him use aliases. Chieri, a popular girl with his customers, who happens to have a sex-friend relationship with one of his other girls, Mika. Mika definitely takes it way more seriously than Chieri, though and it's causing some friction between them.
In the meantime, Hajime has fallen for one of his employees, an attractive, classic beauty who goes by the name Kyouko. Little does the owner know that Kyouko's true passion is writing Boys Love doujinshi.
And then there's Mariko who sort of adopts a younger guy she meets on the street. The next thing we know they are involved, and things are just getting plain weird between them.
