I did not like this ending. It left me empty, and not in that emotional, "the world is cruel" way. There was no resolution. The story didn't end, it simply stated that some situations are better and some are going to go pretty much in the same way. I'm not even bothered that the love interest never resolved to anything concrete, hell, I expected it. I felt no attachment to Satou's desire to love Misaki through his own independence. It became clear before this final chapter that Satou was now capable so the ending was little more than an affirmation a hurdle we already went through.
It didn't feel like an ending. The revelations resulting from character dialogue were no more impactful than others in the manga. It only felt like an ending because of a time skip and some pictures reminding me of the good parts of the story. "Hey, remember these characters and what they did! Awesome, huh? OK, it's all over now." Bottom line, no impact at all.
I loved the manga though, although I rated it a 6/10. But that's simply because I do not see myself recommending this to anyone. Personally, it hits close to home for me. I sympathize with the main character so much that a rating feels stupid. It's not even what I'd think of as a favorite manga, it's just emotionally sticky. A story like this will stay near my heart, where I can reflect on it for eternity.
