Loved the anime back them when it was releasing, remembered about this yesterday and the fact that I never saw the ending, came here and... So much anxiety.
A very open ending, and almost no character development in 300 chapters... C'mon, at the end they still have the same problems they had at the start, the only thing that changed was the fact that he discovered why she wanted to be with him and this is not even talked after the fact, yes he trusts her, but... That's literally the plot of the manga, and it's not discussed at all by the two at the end, she just appears with a hammer to "make him lose his memory"... Pushed too far the comedy at the end, should be more romance focused, such a good manga but as always those endings... Those damn endings.
