I enjoyed this one.
It doesn't feel like it was cancelled and rushed to end, but instead that this was the natural end of the story that they wanted to tell. I feel like it potentially could have run for longer, but I'm glad that it ended when it did rather than stretching anything out. The relationship actually progressed and I like how it was at the end of the manga.
Though honestly I would have been happy to have gotten more chapters of the two as a couple that fights crime. I feel like the dynamic and the history to the characters is fun enough that it could carry a shift like that. But the fact it concluded its story with me wanting a sequel that isn't reliant on any unaddressed plot threads I'll consider another plus.
