I mean....what happened exactly?
They're in love with each other, but they've each figured out that they aren't where they need to be with themselves to be with each other. But they will be once they get their shizzy in order--which they absolutely will do, because true love is on the line if they don't.
That is--without a doubt in my heart--exactly what the ending was: Kondo realizes he's actually in love with her (the imagined running to him and embracing her), and Akira realizes that she's in love with him and using her being in love with him as an excuse not to deal with her trauma (she tells him he's the first one she'll go to when she's done with getting back in form). Which, all in all, is very good way for this story to end: on optimism for reaching a goal, rather than a reached goal.
BUT...
Akira just comes back to track? That easy? I don't know here man. I'm not really satisfied or convinced
...because the show didn't earn it.
As has been fretted over and pointed out many a time, there wasn't enough room to tell what is obviously a very large and very complex story about love and self-identity and pessimism and failure and despair and connection and passion and--so many, many things. If I had to guess, we ran into an adaptation conundrum. They wanted to wrap things up, but they also didn't start the story with the wrap-up in mind. We got 7 episodes of an excellent examination of an evolving age-gap romance, and then 5 episodes focused almost entirely on the deep-seated emotional obstacles standing in the way of that age-gap romance but divorced from the age-gap romance they were supposed to be standing in the way of.
I like the ending itself, though, in that I like how this was a love story and also not a love story. But the sloppy transition away from the romance meant a transition away from Akira and Kondo being the things that moved them both to change. A decision to love each other once they've gotten themselves straightened out is much more powerful if they are each other's reason for getting themselves straightened out. And, as it stands, that isn't the case. At all. It was things outside their connection, specifically Haruka/Chihiro, and...frankly, I don't even know what either of them did that spurred our protagonists to action.
In short: something went awry at the planning stage. Which is disappointing.
That said, I love that Kondo's novel is named after the point in time he and Akira are looking to get together. (Which was a really sweet way to end it. Even if it kind of doesn't make sense that that would be the--never mind.)
And that Yoshizawa's haircut was AWFUL. He's a super-nice guy...or he must really like Yui, even if he doesn't realize it.
