I was hoping for something I could read to kill time, so I decided to give this a shot. I found myself more and more frustrated as I read on.
Only two of the main characters are about as close as you can get to sincerely nice people who care about the people they meet. Nearly everyone is incredibly selfish to the point where the only reason they exist is to mess with the main character because of whatever personal goals they have. This is literally all the characterization they get. There is no character growth or anything, they are all far too stubborn for that.
Every chapter is more or less the exact same thing; one of the selfish characters will try to fulfill their goal but fail in some stupid way, and everything is back to normal. No one seems to regret anything, and they're ready to go do another dastardly deed the next time the spotlight decides to shine on them. The two main romantic pair might get a little closer, but it's so miniscule it feels like the love flags never existed.
Of course, everything that happens is really for the purpose of creating fanservice. But the way they transpire is so incredibly stupid, it's no longer "good" fanservice. It's not even a fun kind of stupid, it's just boring. It's no longer comedic at this point.
The interaction between these two personalities are the same, and it gets old and frustrating after only a few chapters. Selfish character does something annoying, kind character asks them to stop. The response is a "no" and the kind character concedes. That's it. Combine it with how none of the selfish characters seem to succeed in whatever zany scheme they came up with, no one accomplishes anything. Plot progress is an absolute zero, and the most that ever happens is you learn slightly more about why anything is happening and maybe another unnecessary character gets added. But does anyone get close to their goal? Not in the slightest.
I'm probably just as guilty as most of the cast in terms of stubborness though. I'm still reading this stupid thing because I feel like I've already committed too much time into it; I'm already over halfway through. But if you haven't read it already yourself, don't bother starting. Ever.
