And here's a reversed role one (ch. 1-3): http://www.mangago.me/read-manga/ouji_no_hakoniwa/
http://www.mangago.me/read-manga/king_s_maker/
king's maker is more shounen ai but then it has yaoi extras in the end: http://www.mangago.me/read-manga/king_s_maker_triple_crown/
royal servant, black knight, hosik's story(side story), the silent concubine, where the wind stays(i fucking love the real seme), obedient heritage, spinel, painter of the night, my housemate, king's maker, emperor stay here your knight's getting off work, to be or not to be, blood bank,

VERY similar trope.
Woah ヾ(☆▽☆)
