I like that she's still that impulive type who says what she wants, even if she gets embarrassed immediately after.
Old enough to walk around after dark, sure, that's usually a thing here as well, but specifically at New Year's Eve? Everyone gets to be up past midnight. Maybe not long after, but after.
I like how realistic everything is. Feels like a woman made this manga and looking at the artstyle, i might be right. Goes to show that women write some of the best romances (except if it's yuri).
