The reality in Japan is that, young people struggle to form romantic relationships, even if they aren't NEETs or otaku or anything of the like. That's why host clubs and undergorund idol groups thrive. But as you can see, both are hella expensive and also exploitive. The girls have no other choice but to result in prostitution. But there is no actual sentiment involved in either of these relationships. You often hear stories of girls rip off rich but vulnerable men only to spend it all on host clubs. It's a complicated and alarming issue in Japan, that's why this arc is so long. Sorry if it's boring and predictable to you, but this manga has never relied on fictional shock value but always potrayed irl issues as they are. I'm glad this arc is about to wrap up though, curious how the author will "solve" it.
