I feel like this last chapter started off with the completely wrong tone. Time skip endings can be good, like some people have said; they show that the relationship is the kind that will stand the test of time (and distance, in many cases). This chapter pretty much was exactly that...except for the fact that at the beginning it seemed like they had broken up for some random reason and moved on with their lives. I guess the author was trying to fake us out, but it fell flat? The first part of the chapter sets it up to be a bittersweet ending about...I don't even know, learning to love and let go? But then it's all like, sike, she's back now, and they all lived happily ever after! Like, just fucking start the chapter at "Nika-chan comes back home today" and you've got yourself a great ending. This just had me going "Oh, uh, okay, I guess everything's fine?"
But anyway, after I got past the unnecessary fakeout stuff it was a nice ending. Also, maybe I just had the wrong impression of what the author was trying to do with that first part. I am glad they get to live happily ever after, and the time skip itself didn't really bother me. All in all, this series was pretty good.
