You're forced into an arranged marriage by your father, he didn't even give you a chance to at least get to know your fiance, you didn't really know what he's like but all you knew is that the emperor wouldn't choose someone ugly for you so at least there's that. He couldnt care less about their personality

"look.. We both know we'd rather marry someone we actually love but if you be nice to me I'll be nice back okay? We don't need to hate each other because of this arranged marriage."
