When you think about it, Flonne is the abstract ideal of a neetwife.
>Comes to you from parts unknown
>Needs a place to stay, starts living with you as a pseudo adoption
>No real job or immediate aspirations, spends most of her time in hobbies
>Not unclean or messy. Actively makes your living space more pleasant
>Not really a shut in, is happy to go do things
>Emotionally available at all times, deeply empathetic, and is always willing to help you, or tag along with what you're doing
>Mostly philosophically lazy. Actively works to improve your shared living space and make your lives better, but doesn't engage with traditional labor
>Goes to extreme lengths to talk with you and help you through your parental issues, and make you a better man.
>Is never a pushover, never lets you take the easy way out, and carries herself with dignity
>Is working to improve her situation, but never turns her back on you.
It's really incredible how well they did with her
