Sleeping Ranker

I dropped this long ago and forgot why, so I am re-reading.
I reached chap 3 and I remembered why I dropped: this story is FULL of nonsensical contradictions and inconsistencies.
E.g. in just only 3 chaps the idiot MC quits his shitty job irl because he realises he can make money in the game (which btw he should have already realised since a long time, and it’s not like he couldn’t make enough money until now without his newly acquired god class). 
He says he has money left only for two months atm. He proceeds to go to a public internet cafe and pays a HUGE sum of money when he already has a capsule at home, just because he doesn’t want to tell his paraplegic sister that he has quit his job!!!!!!!???
But then he goes home and the first thing he does is telling her that he’s quit!?? THEN WHY THE F. DID YOU HAVE TO WASTE THAT HUGE SUM OF MONEY YOU F…G IDIOT!!!!!?
And the sister didn’t even tell him that she can walk again, and that she is paying her own hospital bills with money she made in the game!? You see your brother coming back home very late and tired every day and you don’t even f…g tell him that he doesn’t need to work extra!???
What a pair of hopelessly ret… siblings.
And this was only an example. I remembered now that the whole story is like that.
This shit is written by a drunk 12 y/o autistic chihuahua. Only such a creature would paint the MCs as complete ret…, making the audience lose respect for them in only 3 chapters.
I guess it can be a half decent time waster if you don’t care about consistency and good writing.
But it’s definitely not even remotely worth the current rating of 4.5/5! Don’t people realise that 4.5/5 = 9/10? 10/10 = perfection, 9/19 = absolute peak. HOW THE F. is this shit absolute peak?
