@kyrex Yeah Kei is so stupid that it's annoying, she's angry at the wrong people, at least the old man is trying to help her while she gave up and committed suicide. Honestly I just want to see where the manga goes with the current conflict.
I see it ending a few ways:
1) Kei finally wakes up from her hissy fit, and after everything is resolved she gets her body back and is able to live the life she wasn't able to while the old man passes on or maybe reincarnates to get a second chance at life.
2) Kei comes back to her senses and after everything is set straight, it is her who passes on or reincarnates while the old man stays in her body.
(These last two are unlikely but interesting)
3) Everything is resolved and both Kei and the old man pass on or reincarnate.
4) Everything is resolved and both their souls merge into one within her body.
