I thoroughly hate young male to older female relationships (I find this trope annoying). In any event, its story and artwork is so wonderful it's become an instant fav... and I still hate it! :-p
Well, she's certainly a really nice person. After finding out about his situation she just does her best to...well, take care of him for a bit until his mother gets home.
Great ending though. And she even offers to help him out from now on anytime he needs it. She's such a nice girl...Maybe once he grows up a bit, a nice...ring would be a perfect thank you gift for her?
