I read it on Cloud Atlas by David Mitchell.

So the xcursion helped dislodge your . . .sense of ennui?

In a way, yes. It helped me understand how one’s environment is a key to one’s identity, but that my environment, Papa Song’s, was a lost key. I found myself wishing to revisit my x-finery under Chongmyo Plaza. I could not fully explain why, but an impulse can be both vaguely understood and strong.
