Okane ga Nai, Volume 1 (Okane ga Nai, #1) - Hitoyo Shinozaki,  Tohru Kousaka I loved/hate this yaoi.
Ayase seems so stupid sometimes... I mean, more than innocent, it's more stupidity than innocence.
Kanou is like a really big perv, buying a younger guy. He is certainly protecting the stupid/innocent Ayase from someone more perv than himself? Probably yes, because Kanou really protect Ayase... but well, rape also????

So, I like it! Ohhh HOT HOT HOT! A guy buying another and using him as his sex toy! But also hate it... For example I hate the drug/alcohol abuse

and the rape scenes (more than one)
