Well... polygamy is not always everyone with everyone though? Sometimes it's more of an open relationship, where they agree on one person dating two for example (with those two people knowing and not having feelings for each other and only for the one they "share"), sorry english isn't my main lenguage so idk if I'm explaining it correctly, they don't all have to have feelings for each other for a poly relationship, that's not an stablished ruled from what I've learned.
But the fact that they all seem to want to be the only one destroys a poly route alltogether.
Honestly just want them all to be happy.
Arth is so lovely, just seeing him go from someone who can't express his feelings to be actually honest to the point of looking smooth is so adorable I love him sm.
In an ideal world she would take Rebecca, Naska and Arth to be her harem lol, but I quite like it if she ends up with Arth... he has done absolutly everything to try and save her and make her life easier while advicing her on being more honest herself.
Hope there isn't any more bad blood between Rebecca and Arth... even though I feel aeful for her seeing as if she was a guy she would be able to be head of her family, practice the sword AND be able to ask for Sasha's hand in marriage like Arth ;; so sad, let her be happy.
