Where did you see this? Luckily, I'm not expecting a follow=up to Last Life... but it does sound like a similar film. I really want to see this.
I went in to this assuming that it was a follow-up to Last Life in the Universe. It isn't, so I was a bit disappointed; however I think this is a really beautiful film. The story can be a bit confusing but it draws your attention regardless, and Doyle's cinematographic style is gorgeous as usual.
