I'm hoping when it's close to ending, he won't be thrown to the future again, doesn't matter how happy of an ending he achieved, since there's no point in having a different timeline if you didn't live through it.
Also it's crazy to think that his first timeline, in which he already married Mika, is now gone forever. From now on, the canon timeline for everytime he goes back to future will be this one where he went insane and accused as rapist. Of course, only if he doesn't change the past (he boutta do now).
Well since it's a manga i don't really complain bout nothing but if i were him i'll just be grateful that my (first and last) life is me happily married while having a stable income.
He have his plot armor so he can gamble to change the past, but me ? Bet my ass i'm just gonna make my past worse.
