I think you all are missing the point. Ayane's strange behavior and attitude has nothing to do with her status as "mysterious" character. She just doesn't know how to deal with people. And the reason for that is simply because she lives on her own.

We don't know the details. For all we know her parents are dead. What we do know is that she lives alone and is not a recent thing. She probably has been on her own for years, so it's natural she doesn't know how to properly interact with others. Rather than being a mysterious character, she's more like a huge dork who doesn't know how to deal with others. She tries to look cool for Sana but fails miserably at it, and then she sulks like an immature little girl, because that's exactly what she really is.
Heck, even her "seductive" behavior with Micchan was probably just a massively awkward way to make friends with her rather than any actual seduction. She just doesn't know how to properly make friends. She doesn't have any after all.
This is why I like Ayane's character. This isn't just about her and Sana being a cute couple (and they are cute, don't get me wrong). This is also about Ayane learning how to interact with others. And in the latest chapters she's starting to become a little more social than she was at the beginning.
Your interpretation, that she's been alone for years and simply doesn't know how to interact with others, is just a guess. There's not really enough information available for us to come to that conclusion. I agree with you that she probably lives on her own, but we don't know that for certain, or when that started. With Suu-chan in the picture, it's clear that Ayane has some friends or acquaintances, even if she keeps them at a distance, so it's not like she's been in isolation her whole life.
From the beginning, the author has been revealing only hints of Ayane's life. She was in the hospital, but she never told Sana why. We have no idea what her family situation is like, except that her parents don't do things that we'd normally expect parents to do. She apparently doesn't go to school, but we learned that through sheer coincidence. She hasn't even given Sana her phone number or told her where she lives, and they've been dating for months now (at least half a year, judging by the changing seasons). Sana has no way to contact her, and that's been an issue in the story several times now. That's inherently suspicious, and doesn't really make a lot of sense if you think about it. In all this time they've never once discussed Ayane's personal life?
Basically, it feels like the author, either carelessly or deliberately, has created a state of affairs where Sana has an unbelievably low amount of information about someone she's known intimately for half a year, all for the sake of keeping us in the dark about Ayane's personal life.
