A cheater's wet dream

I started this manga so many years ago when it still made sense and had a plot... Now I don't know what the fuck is even going on, who some of these people are, why the fuck they're even relevant, and what even the fuck happened to the storyline of the main characters. It's all just a bunch of skinny dudes fucking some big ass dude, and them fucking each other and other people and proclaiming love and then continue to fuck other people. I give up. I'm done wasting my time.
