Writer has the right idea of using emotional and psychological vulnerability, but he also overreaches and tries to make MC look PHYSICALLY vulnerable as well.
The inconsistency is honestly getting kinda annoying. The writer keeps portraying him as physically vulnerable after all the effort he put into making him OP in the start. Sometimes it's for comedy, sometimes it's just for drama, but it never flows well with what he established at the start. You can't have your cake and eat it too. He's better off just focusing on the weakness of MC's allies and MC's own psychological weaknesses.
