Rises the Moon - Liana Flores was my immediate thought. First off? Moon theme. Second, I associate the sound overall with sweet/kind characters. The lyrics are very reassuring, and are associated with endurance, which she seems to have done quite a bit of. Second thought was Moonshine - Caravan Palace, mostly because of the title... but the lyrics seem to fit her story pretty nicely, imo!!
(Sorry for the somewhat basic music... I know these artists/songs are on like every character playlist out there, and I try to avoid that, but her character fits them so nicely I couldn't think up any other recommendations!)
