Playing devil's advocate but at least Hayasaka's arc was mercifully short, had some cute interactions and it paved the road for the final arc, since it sowed how much of a threat the Shinomiya were. Tsubame's arc on the other hand was nothing but a huge waste of time, and had by far the dullest chapters in the manga.
I like Oshi no Ko but it lacked the impact early Kaguya had. Right now I don't know if I should place closer it to Kaguya or to Ib. It seems darker than it looks, despite the sharingan memes.
