Man, the Nagatoro author thing is such a classic case of someone getting famous for one thing and having their back catalogue totally overlooked. The author's name is Nanashi, and before 'Don't Toy With Me, Miss Nagatoro,' there was 'Senpai ga Uzai Kouhai no Hanashi' which honestly feels like a prototype for the dynamic. I stumbled on it years ago on some scanlation site and it had the same kind of mean-but-not-really teasing energy, just less polished. Then there's the whole 'Itoshi no Kana' phase which is... a different genre entirely, let's say. Feels weird how knowing that changes the reading of Nagatoro's early chapters, like you can see the artist figuring out how to balance edge with genuine affection across different projects.
What's actually fascinating is how consistent the themes are across Nanashi's work even when the genre shifts. The push-pull of awkwardness and aggression, characters who communicate poorly but feel intensely. Makes you realize Nagatoro wasn't some random hit but a refinement of an obsession. The earlier stuff is rougher, sure, but you can trace the lineage. I'd argue digging into it makes you appreciate the main series more, seeing what got trimmed and what got amplified.
