honestly I don't dig her flippant and "holier-than-thou" attitude at all. I kept reading in hope of knowing a bit more about what's going on and why she's like that, but it's already the 2nd volume and we barely got a clue aside from "that's just how she is" and frankly, I hate it.
thanks for your effort in doing this but it isn't my cup of tea so I will stop reading here.
He likes her, right? I mean, why else would he come over for no reason like that?
it's been shown that he cared about her grandpa when he was alive, so he's probably concerned about the grandpa's house. Though he probably cares a bit about her as well because 1) they've known each other for a long time and 2) even if she sucks as a person, she's still the grandchild of someone he cared about.
