That's actually the only piece of Murakami that I liked, despite the abundance of erotic scenes. (didn't read highly recommended Kafka on the shore though yet).

Also damn Tomoko just casually thinks Yuu is "looking sexy as usual", that's so friggin blunt...she's either really honest with herself or just incredibly oblivious.
Pretty sure that rushing with adult things in your childhood can make you scared for life so take your time to think about what you want and what you are doing.
