I'm a big fan of "non-humans in regular environments", so I'm definitely hooked on the idea of an eldritch entity adopting a girl. Or, in this case, a girl adopting an eldritch entity as her parent. LOL.
Although short, I'm already intrigued by what's happening and how things could go. No pressure to continue the story, of course, but thought I'd add my coin to the well. Hahaha.
