I'm looking for a yaoi, all i remember is that at the begining, the morning following the uke and seme having sex for the first time. Seme came to the uke (who was awake and still in the bed i think) and he threw money at him. At first.the uke was offended but it was later known that the seme wanted to give him a ring but didnt have one so he threw money instead xD
