Man, this story is just incomprehensible so far.
1. The protagonist doesn't want to change the original plotline of the game, apparently because he thinks knowledge of the game's story gives him an advantage. But, the fate of his character in the original plotline is defeat and expulsion, so why the fuck would he want that?
2. The protagonist has crippling self-esteem issues for some reason. Why? He was incredibly good at the original game and has tons of game knowledge that apparently no one else is privy to. There's no reason for him to have bad self-esteem. At least none that has been told to the audience.
3. The facts about this world and how it works are just a huge mess. Like, the FMC is the childhood friend of the MC's ingame character and they promised to marry, but the MC doesn't know this for some reason, despite having played the game? The MC is also unaware of Butao's family and relationships. Butao is apparently not a bad person, because he was nice to the FMC when they were kids and he loves and protects his family. But he also got fat and lazy and started treating the FMC like shit totally randomly. Like, wtf is even his character? These inconsistencies mixed with how random and incoherent the RL MC acts just makes the story so frustrating to read. Maybe this is intended to be like a mystery that the RL MC gradually unravels, but it's presented in such a convoluted way that it's just annoying.
4. In this last chapter, the MC tells Akagi that he respects him, and the FMC gets mad at him for that. Why? Makes no fucking sense.
5. The MC keeps saying things like "this is convenient for me" when completely disadvantageous things happen. But it's extremely unclear how it's convenient for him. Because his plan is extremely vague and poorly explained. And he constantly acts in a way as if he has no plan at all and is just having a nervous breakdown, so switching between that and this persona like he's got it all figured out is jarring and confusing.
I dearly hope this story gets its shit together at some point. I can't stand it if it's gonna continue like this.
