having a bit of time to think about it, this is a debate between those who enjoy the story despite the negatives, and those who cant enjoy the story because of the negatives.
so, it goes without saying there will be no agreement, since those who like the story despite its negatives will focus on the positives and dismiss the negatives as no big deal.
I think it boils down to how much you think trauma and other external factors as intense emotions deflect responsability for our own actions.
If you believe that no matter what we're masters of our actions ergo we should be held accountable for them no matter what, you're more likely to find shiho, her development and conclusion lackluster and poorly written
On the other hand if you think that emotions are things that are completely out of our control and it's ok and only natural to succumb to them and their most desteuctive impulses, you probably will find the shiho plot relatable and not as flawed as other people think
Also I'm gonna allow myself to be a bit of an asshole here. If you don't mind poor writting as long as beautiful illustrated and portraits really strong emotions you're more like to like this arc
