For some reason I am cheering now for a Kaoru/Risako ending, even though I know it's impossible. Kaoru/Uta is too awk at this point.
That's cool.
But afaic, hooking them up together is just a pitiful cop-out (if I may be so bold as to project my real-life angst and ministrations).
I'd say Kaoru would be better off divorced and single for a time-being, venture into business just to have her own money (self-reliance), then go fuck any dude or dudette she deems hot. You know, just to get a semblance of self-ownership. Just to get her back to her feet.
Risako can just stop this fake hyper-almost sociopathic-rationality and try to feel by going to extremes: go overseas where weed/marijuana is legal or any psychedelic shit, join some decent sex orgy in some European city, become a nudist environmentalist. I dunno, maybe write a song or fucking do some art, do some bungee jumping or parkour. Feeling something is her problem, right? Then try some extremes. \
Reiichi can still go to hell for all I care. Or spend his time becoming a UN volunteer in refugee camps. Find some worth, dude. He's basically useless now.
Except for Kuro and Miyabi the rest should stay single.
