Hi I'm looking for two yaoi manga's, and i just can't seem to get them out of my head. please help me find them

1. its set in a time where japan was at war and they lost. there were complicated politics but the uke used to be a noble (?) family and a noble from the winning side came over and demanded his sisters hand in marriage / the sister was already engaged but the fiance was away fighting i think? any way, the uke offered himself in his sisters place and then him and the seme had sex. another scene was when they desperately needed medicine but the noble refused to give it too then so the boy had to sleep with him. it wasn't paedophilia because I'm pretty sure they were both over 18. but then the war finished and the fiance of the sister came back and the noble couldn't threaten him anymore but they still stayed lovers.

2. not remember much about this except that the seme had black hair and the uke had blonde hair. seme and uke were childhood friends but the seme raped uke and brought him back home unconscious and the brother of the uke punched him in the face.

Thank You.
