A yaoi manga were the uke meet the seme because the seme wanted to work in his mother's place work (I think she was a mangaka) the work place is in their house and all of the workers are girls. I think the seme had a tattoo on his back. So, they get near to each other but then the seme saw the uke kissing a guy(the guy is uke's friend and he was just broke up with his lover (he's a gay) so the uke wanted to help him but his friend kissed him and said that he is sweet) so the seme got angry and left. The uke run after him but they didn't get together. Then other day the uke was pushed down by his gay friend but again the seme saw them but this time he punched the guy. Then they got along and became lovers.
I remember also that the uke has older sister that he loves so much because she protect him when they were kids. So, when his older sister get sad because of her lover ( I think a business man) the uke got angry and punched him. But then his older sister get along again with the man.
Sorry for the bad English, hope anyone can help!ヾ(❀╹◡╹)ﾉ~
