Review Detail of MMickkWeeb in Shadow Slave

My thoughts on the story as of 210ch the main character keeps making less and less sense and I have no idea why this happened. Like what changed in the MCs mindset from trying to reach the castle to actually getting into the castle. The mc now randomly has become the punching bag of the story, everyone uses him and now he's even become compassionate to everyone I understand his mindset toward Neph and Cassie but what about the huntress and kai .like how has he become a true idiot in 50ch or whatever. Maybe this was explained in the random 30ch flashback that was probably the worst executed flashback ever so I decided to skip that part of the story. (Like why would you ever do that flashback when we already pretty much figured out what happened why couldn't you just do that random 30ch flashback at the start when it made sense to do it.) When I first saw the cassie and neph personality changes I simply expected them to get killed at the end of the arc as you could see that he was started getting used as a dog by them but at this point, I don't even expect that to happen with how randomly 180 this story changed from mc being a rational cold human being to becoming a (crazy???) punching bag. I guess this storys name is shadow slave but at the same time how stupidly you made their personalities change is absurd. As this shit went from me loving neph and cassie and the trio as it was very wholesome, to me now begging that at the end of the volume they get killed. My last hope is that the plot somehow turns out like soul of nearly but expectations are not high
