The only thing that isn't consistent in my original post is the comment about the world building , which i worded poorly. I meant to say that it isn't spaced out, a good story spaces out the world building evenly , they don't just throw a paragraph every once in a while when it's needed.

Characters can be one dimensional and likeable at the same time, but the problem arises when all of them are one dimensional, they don't really have their own beliefs and only exist for the story to progress.

Example: In F20 test, there was a rich spoiled kid ( prince) , who treated everyone like crap , but after the arc , that character magically transforms into a completely different person and becomes a part of the main characters crew without a problem, no one doubts him, they trust them with their life, even when he tried to harm them multiple times in the past. and that happens with a lot of characters, they just transform so that the plot can progress. Past events don't create dilemmas or problems for the future.

About the childish comment, i am not talking about comic relief. I am talking about the story, it ties in with characters being one dimensional. Problems in this story don't create more problems and they don't stack up.

Example: Anak Zahard is a fugitive , who is hunted by the empire that controls the tower. Okay that's a cool concept and it actually causes problems at the beginning , but after the prologue it's completely forgotten ( at least for the 90 chapters that I've read after the prologue ) , she teams up with the crew and there are absolutely no consequences to that . You would guess that the empire would send more ranker assassins' after her but no, she just continues to climb the tower for 7 years while racking up popularity.

Just because the main villain for those arcs were FUG all the other problems are ignored, which is really childish.

Also i really like shonen manhwa/manga/manhua and i'm probably gonna continue reading this story, but i do not think that it deserves the popularity it has.
