@jak I don't think it was so she could be with Shimao. She said she felt like she was the cause of Shimao and Hazuki's pain so she probably thought if she left Hazuki could be happy. Not saying it makes sense, but grief does things to one's brain.
@rellea - I mean I guess you could look at it that way, but it just felt weird because she confessed to have fallen in love with him right before that. Considering how she was when Shimao died, you think she wouldn't have gone down that path because she knew how it would affect him.
@ejxs - Yeah, I don't get why he didn't pass on either. You think he would have after the forest incident because he finally let go of Rokka.
