Its kinda like this manga actually, some surprisingly deep and insightful lines wrapped up in a wholly off-putting delivery
Been musing a bit on how some folks mentioned how "be normal" doesn't work as advice for the men who most need it and been thinking of it in terms of implementation error. Like it would clearly not work for the horrible leery co-worker b/c he doesn't see anything wrong with his flirting and groping. So yeah it's less advice and more permission structure - FMC likes Gomi cause he's (mostly) normalish so he shouldn't pull back and what's holding him back is "women are lying and manipulative" paranoia.
(ETA: just to be clear, I'm trying to say that I agree with what folks have been saying about how decent guys generally don't need to be advised to be decent, not that guys who don't get girls are awful.)
