Out. This is another fucking shoujo pretending to be something mature, cherry top'd with "i like you" line and angsty teen-like quality 'philosophizing' about 'what's normal'. 
The signs were there of course, with all the two dimensional flatness to characterizations and whatnot, but holly shit, that phrase coming from a person who'd left high school more than decade ago was just too much.
Wish I could've rated it lower than '1', it's just bad.
edit: oh, and there reason she's not leaving? Japan's not California thankfully. Pureness of yuri romance takes a backseat when confronted with financial burdens of day-to-day life. At least the author got that part right.
