Sultan ~The Lovesong is Forever~

In a semi-fantasy world set in a sort of medieval time; our protagonist grew with his siblings and friends after their parents died. After many years surviving on the streets, they are met by a couple of people of soldiers who take them straight to the king. The king, upon reviewing them, tells our hero that he’ll be next in line to succeed the throne! It turns out the hero is the old man’s lost grandchild. Now the royal court is either up in arms about the new prince or frantically trying to find him a suitable candidate to be the future princess. Who of the lovely ladies will be chosen by you--or will you pick his childhood friend?
