Nahh, I understand you but i think Camille is the only still better be the future wife of MC ,
That barbarian girl literally still wants him even tho she knows he has a fiancé and she keep wanting to take him, and since she already said her goodbye, it better than ever, also I don't think his family approves barbarian as his future wife,
As for Camille she indeed has a ridiculous thing to make a contact with the demon, but if you check it again, that because she almost die , she can't move for so long, and that demons is really save her that time , and also MC sword isn't that technically demon ? So MC and Camille literally the same species half human half demons

Istg, I only like the barbarian girl..
I like red hair girl at first, but she choosing to make a contract with the demon is stupid af..
The sudden soulmate shit with the saint (she indecisive too, liking vikir and night hound tho it's same person)
And sinclair. She saw they fighting the damn demon (his dad) and even after seeing that still mad at night hound, understandable but still making me mad.
Atp if you didn't ended up with the barbarian just cut ur dick and be single bro
