Comments of chapter undefined of The Angel's Demon (BL)

Is there no rules against arranging an engagement without asking the ppl envolved. I get that during these times and with nobility the parents are usually the ones who choose the person who there kid married. But they think the MC is from another country and supposedly his parents aren’t there. So can they just make the MC Marty there daughter even without asking the MC supposed parents from the other kingdom. Like shouldn’t they at least ask the MC or they think the MC is a human prince, so shouldn’t they at least ask the MC human “parents”?
