Back when it first came out I saw occasional threads for it on /a/ and hoped into it because the main girl looked like a meme, it seemed like a typical "will they won't they" that never actually leads to anywhere. I eventually dropped it after 20-ish chapters because it seemed like nothing but softcore femdom shenanigans.

It seemed like a school boy fantasy."What if the hot girl in school who constantly bullies me actually likes me?" kind of scenario, having never been a school boy before and hating every single ugly pig face slutbag who bullied me back then I couldn't get into the fantasy. It didn't help that Nagatoro was kinda meh for me design wise.

With the anime adaptation coming up I decided to take another crack at it and, yo, tf is this??? Actual romantic progression in a ecchi manga????? I was pleasantly surprised.

Oiginally I hated Nagatoro because she was a giant (or rather tiny) biiiiiiiitch, but reading it back to back made me realize that she's just a shy dork. Personally I prefer Gamo but I can understand why the main lead is more popular compared to the smug lord who only appears every 10 chapters or so.

Nagatoro is somewhat of a tsundere but actually well executed, a well done tsundere is super rare to see in these type of manga usually.

She constantly makes fun of or tries to downplay her crush for the first 40 chapters or so but once Senpai catches on it moves further and further away from a ecchi manga and became more and more a genuine romance with some sexy stuff in between.

The first two chapters are kind of strange to read now, their relationship has developed so much and Senpai has grown such tough skin that it's weird to consider him actually being afraid or disliking Nagatoro.

For those who gave up or are considering giving it up after 20-ish chapters keep going, after the cultural festival it gets really cute and fluffy.
