Thanks translators for staying with it till the end! Came here after reading epilogue, which is certainly better than this last chapter (for the most part). Overall, it's an ending, everything is done "as it should be", to a T. Both main points people discuss in comments are valid.
A. It's a cosplay manga first and foremost - thats true, author stated it many times, it's main focus. But it got traction due to a pretty female lead and great anime adaptation.
B. Romance went downhill practially right after what was adapted in 1st season of anime, barely existed as subplot, not even talking about scenes together. I was one of few people that defended Haliel arc, as a really well explained bain of perfectionist, but did it paid off? Nope, in the end both crows got barely anything.
Guessing anime only folks won't even see end in season 2. Well, hopefuly anime will be great anyway.
Congratulation to author for making it a decent happy end, not all mangakas managing to do even that.
