Gotouge

Following its debut in February 2016, posted its final chapter in 2020, and Gotouge has yet to announce any sort of manga comeback.

And, while fans appreciate that Gotouge confirmed concrete pairings in the final chapter, similar to how did it, most of these relationships hadn't built up any real chemistry throughout the series, especially Nezuko and Zenitsu.

Though, the more people look into it, the more it becomes pretty clear that Gotouge decided it was time to end the series and rushed towards that finish line.
