Fucking bastard and Sex Friend

Ookane Hajime is a college student who sells his body to earn money and school credits. The man he fell for is Kanzaki Takara, the worst kind of scumbag who cheerfully brags about getting caught cheating with six people at once. Despite dating anyone and everyone, Takara refuses to be more than just a casual fling with Hajime. Hajime spends his days feeling frustrated, but even so, he can’t walk away because he’s in love.
