This is playing like a typical harem situation, but at the same time I see no harem tag and it doesn't FEEL like a harem series with how characters aren't built on tropes. So many options for this story.
"Winning over Kunon"? Sorry, you've already lost, he's gonna be winning over you three instead. Either he'll make a Kunon faction they'll join, or he'll just remain independent between the factions.
I love how all 3 factions immediately came to a silent agreement that that place is a safe haven for everyone and left without a single word to each other.
