Apparently Noren is also de-aged but still!! I was hoping for a family reconciliation here. This ending with Juzo being young again feels like it implies how he chose to be with Noren more than his fam.
It was super obvious that she was gonna be just like him the whole time. But yeah, the ending just feels forced and lack luster.
But I completely disagree with your ending. It isn’t even implied that they found a cure yet so how else is he supposed to turn back permanently? He says many times in the series that he needs a job to provide that’s why he took this job. This time, he’s away from them. He said his thanks for everything and stepped away from those important to him, again. For their sake.
I don't care what you guys say but Suika is the main character here!!!!
