Kashikomarimashita, Destiny ( it's omegaverse though)
IDK when you posted but perhaps the people online at that time do not know any manga you wanted plus the it's too specific so it's not common.
http://www.mangago.me/read-manga/ouji_no_hakoniwa/ this is one amazing dark psychological manga about a fallen young master.

The relationship starts like this but changes to the end.
If I remember correctly, "Blood Bank" fits the description. :)

Hello

http://www.mangago.me/tag/master+x+servant/
No one replied to me before :(( but im giving this another go, so can you guys give me some reverse master - servant yaoi plots? where in the master is actually the one that ends up taking care of the servant (or bottom) and maybe even spoiling them? Something like in royal servant or to take an enemys heart thankyou vv muchh!!!~
