Pink Heart Jam, Vol. 1 (manga)

For college student Haiga, starting school in the big city is a chance to make new friends and try new things. On the first day of classes, he spots an impossibly gorgeous upperclassman named Kanae strumming a guitar and decides to join the school’s rock band. But later, when a drunken dare gives Haiga the opportunity to visit a male brothel, he finds his crush employed there as a sex worker!

Haiga lets Kanae introduce him to gay sex, and afterward his innocent crush on Kanae is replaced with a whole new type of attraction. Even as their bond outside the brothel strengthens, Kanae will only be intimate inside its confines—and only in certain ways. What will it take for the two to go beyond experimentation and forge a real relationship?
