ML is being referred to as the "king" of zhenbei in the language i translated it from. Just think of it as "prince"; I didnt want to change the words too much. Also, yes, ML wanted YU to become his "imperial consort" and the emperor knows him as such...hence the the title for YU.
can someone clear up something for me? The new guy is the emperor okay, but ML is also named King, how? and Yu is an "imperial" consort?
