While you're not completely off point , no matter how you flip this burger you have to take a step back realize that there is some truth to other's points of view.
The fact that someone's invested enough to reach chapter 85 is still something so at the very least their point of view might be worth considering.
With that said boys and girls, how about you suck it up ya babies, we're all in the same horrible "waiting for another chapter boat", stress is likely to bubble up lawl.
To be honest the past 15 chapters, if not more, it did start to feel like we're going through either some extensive world building or some character exposé with a long a** backstory. While everything was going down new characters being introduced, more of the cosplay world was expanded on which is really good to stick to the main theme of the initial plot but there's a sense overwhelming familiarity, the filler episode, the arc that's annoying or in-between that won't go away, that's where we are right now!..
I think that's because most people side with the main characters, who had top 5 best development ever and it was so good, natural and not some overdramatic shtick that you wanted more, however this is a manga so, detours are expected, the moment other characters come into play you had to see this coming.
And to make it clear why no one should be shouting at each other, how many bait-and-switch do you need before you learn your lesson?
Marin and Wakana had plenty of opportunity for development but boy/girl shaningans have to happen, "I`m not good enough", "How do I say it?" you know the drill
This manga will go from a 9 or an 8 to a 6 before it gets to the good part.
HENCE we're in the same sucky boat PEOPLE
