Read 1300 chapters before dropping.A fairly solid read. Without spoiling anything, These will be what you need to know:
* Main charcter stays cold, calculated and wary of strangers through and through.
*Other than some girls crushing on MC, almost no romance.
* Action is present towards the end of the arcs lightly but action is not the key of any arc. The story and plot twists are what make this novel a gem, if it is one at all.
* The author does not have the habit of building the worlds in detail. He puts them into dialogues and you will miss a lot of the story of you don't attention and skim over.
* There are fairly good plot twists in every arc, but almost all the villains are one dimensional dumbasses who go into c*cky monologues thinking they are the sh*t before dying.
* Don't expect jumping from game world to reality and vice versa like other novels. Reality is inconsequential.
I dropped because it's like watching Fairy tail. Same story formula applied over every arc.
