I liked this. I was worried it would either be a) run of the mill overly introspective mid-20s "I don't know what to do with my life" crisis, or b) poor me I'm trying to write a book and living with my parents middle class white person woes. But it wasn't either.
The story is: she leaves Japan and returns home to live with her parents while she works on a book. It takes a while, some minor things happen along the way, then she finishes her book and decides what to do next.
It's really kind of nice. It's very peaceful and quiet, not at all twee or angsty or dramatic or cloying. Plus she's a big Hall & Oates fan, so.
