rainier here is in love with the princess of leventhorp which is a hated rival. he convinced her to help him kill the previous king in an attempt to claim the throne but ~chivalric managed to snag it from him before he could get the crown. as the eldest of his house with the need to produce an heir, the beard would be someone he's pledged to be married to, for appearances sake. he plans on marrying the princess when he gets ahold of the crown and creating an heir with her but pressures around him have made it clear that he needs to show a connection with someone else so that no one bats an eye at his dalliance with freya. he would guarantee land and gold for her efforts once he becomes king.
