It's weird because, you know who's causing all this confusing crap going around, and yet that person was in a vegetative, chronically ill state probably from the very beginning.
Like yeah, sucks for whatever happened that got you into that state, but when you decide to pull people into fulfilling your wishes against their will, can you still be sympathetic to them after that? Pitiful, sure, but it doesn't excuse what an incredibly selfish action they caused against others.
At this point, MC is better off being with Kaede and wishing Himawari the best from waaaaaaaaaaay afar.
