It's more that she won't let them give her anything beyond taking care of her actual needs.
They are providing her with food, clothing, housing, and some spending money, and allowing her to work and study as she sees fit; frankly, I'd be happy as a clam in such a situation.

Well summed up.
I suspect that if they felt she would accept it, they'd be providing her with a larger sum of money for her personal expenses, but they've correctly judged her in regard to what she'd accept.

I haven't seen the original, but my suspicion is that this subchapter stuff is a result of the scanlation team not wanting to put off updates any longer, that in actuality the chapters are not broken up in the original.
This would certainly explain why the endings are abrupt; while occurring at a break in the action, they weren't actually intended as a break in publication.
But, as I said, I haven't seen the original so I could be wrong about this.
