The other side of the pair! Wisteria the love interest.

A Duchess rumored to be cursed after her previous two husbands died shortly after marriage she's seen as a social piranha mostly excluded from social events. Which is fine by her, she could just as well be cursed. Except it's not fine. Isolated and alone she's achingly lonely for anything in her life. So when she finds an injured stranger it's only natural to help. The fact it will take a while for him to recuperate is just as well, it'd be safer for him to stay here and not move around so much right? It's just a bonus that Leo have so many stories of the world beyond her home and is so eager to fill the silence.

Wisteria never got over her grief, stuck in limbo were she was just reminded of her loss every time she made an effort to go socialize. Before her loss and still after she's a very curious person, getting lost in books and eager to learn more. Fantasizing about traveling and experiencing the things she reads herself. Personality wise she got a kind and selfish heart, wanting to help people in return for a sliver of gratitude or something new learnt. Often it's more subconscious than something she's aware she wants.
