Can someone help me find this Yaoi? So basically the uke is rich and his boyfriend who is super nonchalant is basically mooching off of him, but wants to break up or something like that, but the uke doesn't want to. And the nonchalant boyfriend has a sadist older brother who is interested in the uke. Please help a sista out!!! T-T
