I've a thought Author if the MC marries Jenna and in future decides to take the irony throne then he'll also be a usurper and if I remember correctly Prussia culture abhors usurpers, so you see where this is going right your reply can be considered a spoiler but is there a hint of second marriage and that too with Targaryen family?
this is one of the reasons why mc insisted that his foreign title of king in prussia be recognized,since mc is the king of the prussian state which is not part of the seven kingdoms,but is the paramount lord of the reach,mc can use the excuse of a war of the states, prussia against the seven kingdoms and not the reach and the seven kingdoms, because one is a war of states and therefore would not be frowned upon by his men, unlike the rebellion if he were only the paramount lord of the reach, but at the end of the day this is the excuse that mc has to justify his attack on the seven kingdoms.
Blasphemer_reader:I'm sorry if I don't remember correctly it's been some time but hasn't he sworn loyalty to the throne, that will automatically make him a usurper.
