The plot has barely progressed, and at this point, it feels stagnant. Every chapter seems to repeat the same events, yet we're already at chapter 70, and the protagonist is still stuck in the same cycle. While the artwork is impressive and the dialogues, though somewhat cringe-worthy, are tolerable, the actual plot development is lacking.
I initially continued reading because the premise was unique and had potential, but it seems the author struggles with advancing the story. It feels as though they are deliberately dragging it out to extend its length. Unfortunately, despite my patience—I’ve waited five to six years for an anime, so waiting for a story’s plot to develop is nothing new to me.
I'm not asking for forced romance, but at the very least, I expect some meaningful action or progression. While I enjoyed it at the start, it no longer holds my interest.
