Most people don't realize Ryen is a king at first. The majority only learns about it when they're told about it. There aren't posters of Ryen's face in Dorgania, so that everyone knows what he looks like. So how should they know?
According to my thinking, what if, one of the four of them was sent to Aldyin to give the produce of bitterrood farming, and in front of the palace they met Ryen. She who was sent then called ryen with the usual nickname, and the soldiers immediately rebuked her for being presumptuous, so what do you think? is this idea suitable?
I suggest that the chosen one is the big boobs bookworm dark elf XD
