Honestly, it's a breath of fresh when manga and maybe Japanese society place on too high a pedestal being a too formal simp, as if that was any useful in the real world.
I was pretty impressed by the structure of this first chapter, greatly showcasing the protag's issue, how he even let himself be used in a platonic relationship (which he saw, as is custom for virgin simps that lose their shit when a woman vaguely talks to them, couldn't but saw too as a means to an end).
We'll see if it will bring back to mind the early days of Pick Artists discourse and Red Pill rhetoric, before it went too far, too delusional and too cringe with gross generalizations.
I remember when I was younger that learning about the concepts of kino (touch, to create rapport) and gradually showing interest blew my mind when it was basic and obvious in hindsight. Like yes, you're never going to closer if you're never taking small steps at a time to close the physical distance, and see if the response is positive or if you figuratively and literally should back off.
And it made me abandon confessions out of nowhere. We've been brainwashed by romcoms, it's not romantic, it's usually confusing and awkward. You can't just throw your feelings you might have built up all on your own about a girl you don't really know, right at her feet out of nowhere and expect her to know what to do with that shit. You gotta give her multiple opportunities to see what's going on and the time to wonder if she likes your interest in her.
And looking out at the situation in the bar that impressed him so much, I think the explanation is simply the cliché that confidence was key. Instead of doing like the simp and assuming that those women were too good for him and unavailable just because they're pretty, blud just went to them and actually talked to them, made the interaction pleasant for the whole group before even focusing on the one girl.
The simp is too in his own world and not engaging in reality. It's wild that he convinced himself what he had with the gold digger even looked like a relationship worth taking to marriage.
