Review Detail of InHisName in Death Game Dating System

For one, this isn't actually a romance novel. Instead this novel is completely serious mystery-thriller/horror genre. Which is brilliant really. Doubly so when the system's main function is one of those revive systems (loading into previous save point.) However the characterisation of the protagonist is unreasonable. So unreasonable that it's just down-right annoying. The author has the protagonist become better (in mental capacity, critical thinking, and power) by 1% every time he dies. So even after 8 deaths the protagonist doesn't really change much. Sure the author describes that he has changed (using terms like mental plasticity), but in reality? He doesn't. Worse, the improvements are maybe evident for one chapter, with the protagonist himself bashing his own naivety, and then...? He regresses into an idiot again. He repeats the same mistakes. He plays the hero to the same consequences. This protagonist is a marvel of poor characterisation.
