Yes, bitches. I don't see any "helpful" action, wonder if your eyes gone wrong but I guess it is when you have to mention "pretty". Also, seem like you misunderstood something. For now, I'm quite satisfied with the storyline because they doesn't interrupt much but I'm asking for a spoiler instead of worthless comment. I want to know whether they going to be annoying in the future.
Not sure what route the webtoon will take, but the novel has harem. (Although most of them are quite strong instead of being useless and sticky.) The webtoon omitted all the harem scenes in season one, so it may or may not continue this way.
As a harem hater myself, I actually quite like the novel because the action scenes are too good. :3 The MC was too badass. (⌒▽⌒) I just skipped the girls and read the action.

Can anyone spoil me about his harem? I hate harem. I'll decided whether to continue or not depend on how annoying the btches are because the storyline is so good (for now).
