Hmm, what an uncomfortable read.
First of all: Be warned, this book contains mention of, and I think romanticizes, suicide.
The first two thirds of the book, the whole story was described by two men, who I think behaved fairly creepy and generally shitty. They both describe the protagonist, Yong-Hye, through their eyes mostly. There's violence, and there's sex, and it doesn't sound like it's consensual.
The third part is less violent, and is told by a woman, Yong-Hye's sister. It also revolves more about Yong-Hye, and at the end, I think her sister is the only person to emphasize with Yong-Hye, at least for a brief moment.
I dunno. I'm pretty bummed out by the whole suicide theme. It probably is a thought-provoking book, but I can't really think about its implications without stepping on these "romantic suicide"-track-of-thought mines.
