Read up to chapter 453.
There are 5 year olds with more "EQ" than this guy, one second he is saying smart things, the next he's a m*r*n. It's bizarre, it's a shame as the rest of the novel is good besides the unlikeable MC. Even when he is 20+, is doesn't get better.
I think an even greater offender is how much effort the author puts in to try and blend plot armor in 'naturally'; he will provide robust explanations and cover every angle to make it reasonable as to why the MC is safe or will be safe if he does X, Y, Z but all it does is kill narrative tension and come across as too convenient; the universe perfectly aligns so the MC experience no setbacks.
He constantly shows off and garners attention while apparently wanting to keep a low profile but never suffers any losses which further exacerbates the lack of character development. So weird when I want something bad to happen to the MC so he can grow up.
