This story setting is in the past so incest relationship doesn’t matter in the past since obviously a lot of people in the past was in an incest relationship mainly to persevere their bloodline and to keep it pure. It’s still legal in Japan and other countries.
Also i agree it made no since that she was even a candidate since she did receive marriage proposals from each candidate so she will end up being an empress either way. But i guess her grandfather probably did it to help her come out of the manison.
maybe it’s like she’ll have the authority of the king but be referred to as the queen since she is a female ( so if she marries them and become queen she’ll have less authority)
Yes, it is. Technically two of them are her uncles and the other a first cousin.
What I don't understand is why couldn't her father/mother be the next sovereing. I mean, one of them has to be the late king's child, right?
first isn't this incest? they're all apart of the royal family making them all related in some way,
SECOND WHATS THE PROBLEM HERE?
its very obvious that the mc shouldn't be 'king' ALSO she could literally get married to the person of her choosing and become queen if she wanted to, she has marriage proposals from all of them doesn't she?
