Got the final volume of My Dress-Up Darling last week. It's a decent final volume, but it feels a bit rushed and disjointed.
Still, I loved the overall manga a lot. My favourite arc is the Haniel arc. I think the mangaka did a stellar job portraying the haunting captivation the characters had for that fictional manga character and thus managed to captivate the reader too (at least for me). That's gonna be tough to adapt to anime.
I'll probably reread the entire manga soonish.
