I dont remember the MC being so fucking childishly stupid; like, he was a salaryman?
He acts like a 10-year-old, not 15, not 25 or 30... like a pre-teen understanding of the world.
I just can't understand any of his actions, reasoning, or thoughts; none of them match.
It's like watching somebody call a cow a toothbrush, and then plugging its tail into a light-socket in hopes of making bread; none of those things work that way.
None of the things the MC says work the way he thinks, says, or acts.
