Soo...was her grandfather just playing matchmaker when he nominated her, knowing that she'd want to get to know all three of them better? :\
This would have been more interesting if she was actually a viable contender. Maybe they'll solve everything by actually making her queen and all three are the king consorts. I do know that it's icky that she's related to all of them.
I thought they're the male leads until I realized
...they're all related to her.
Back then, marriages between cousins are common, but still weird. I don't like the MC much but the plot seems OK. I'll stick around to see what happens.
Wait... So one is her Cousin, one is her Uncle, and one is her 2nd cousin? And this is a reverse harem? Someone please tell me there's a illegitimate child/adopted/not really related storyline later or this is going to get really weird.
