A Lord and his Assassin

Slash!
19 year old Alvar has a hidden life from his family. He has a large family, of all sisters except for the youngest, and no father to provide for them. Most of his sisters were married off, and he could do nothing to stop it. Until he can. His mother requests for him to give up everything, from his life to his freedom, so that he can save the youngest two from the same fate as the other. They make a deal that he has no choice but to accept. If he can get Lord Kaysar to choose him as his bearer, then the girls get to marry for love. If not, they will be given to whoever can pay the most for them. There's only one catch though, if anyone at the castle finds out about his job as Orrick's best assassin, he could loose his life. Can he hide himself away from not only a lord, but a knight, as well as the sudden eyes of the court? Or will his life, and that of his family, be forfeit as payment for his crimes?
