Relationships

Kiara - Kiara was initially very cold to her when Yua first started working for her, which made Yua bitterly thought she must've hated her simply for being a werewolf. It turns out though that Kiara actively distanced herself from everyone because of her immortality, forcing her to eventually say goodbyes to the people she gets attached to. Yua felt bad for her after the misunderstanding was cleared, and stitched her a wolf plush toy make her feel better and open up. They're much closer in the present.
