If it wasn't interesting I wouldn't hunt down this forum and comment about it. And protagonist being Dumb brute wasn't a criticize . I was just sharing my observation.It never said this guy is the best bodyguard out there just a high recommended one he isn't perfect people make mistakes. Having a perfect MC with the story this game has would be boring. All the points you bring up yeah make sense from a logic stand point but that would also be boring to let the MC be too perfect imo. The way these mistakes are made are not only believable but makes him actually feel like a character and not someone that always wins.
These things obviously made the story very interesting
