I missed that era where manga used to have fairly short chapters but genuinely satisfying ...

Actually like the manga after went through the entire chapters. Genuinely didn't expect Seo to be so doting on him albeit he's trying to hide it. I love this kind of characterization because it gave some sort of depth to the character - like how Natori also developed into more than just a character that have fetish on crossdressing av. First look seems like some nonsense manga but eventually it gets better. Manga always manage to spin superficial character into something more wholesome. This is something that's difficult to find outside manga genre. Anyway that's my view
