I'm not a big fan of the ending, it's a bit underwhelming, but it could have been worse, at least we didn't have a ton of fabricated drama for 50 chapters before it.
It’s a decent ending I would love to have seen them in a relationship or something but it was supposed to end this way I presume. A good ride and hopefully there will be more good manga like this in the future.
I was kind of hoping that the reveal would be that she was the one who cried when he stared at her as a kid but this is good as well. Shame it ended, but all the niche good ones do, while crap like one piece are still running.
