Does anyone know this bl Ó╭╮Ò

It was at like old war time, top have a silver/buish long hair with golden orange eyes, botton is a buff moreno black hair guy,

Bottom is a soldier/merchant? And he got called to the palace I think? By the too cause top saw him kill someone,

they went through tons of things like top having a sister that looks exactly like him and they hide that the child they claim to have together is actually not, that it's just part of a plan

then in the end he top becomes the king I CAN'T REMEMBER IF THIS WAS A FEVER DREAM OR REAL
