It ain't perfect, but it is a lot less shallow than many of you are making it out to be. The art is pretty good, which is sadly a bit less common these days, and while the means and methods of how the main trio's relationships evolve are somewhat one dimensional, how the relationships are displayed can be unexpectedly intense.
MC is a bit of a twat, though it's definitely fun to watch him rile others up so ruthlessly. I can definitely feel the contempt for the world and the people perpetuating it coming through. Dude is a dick...but he's fun sometimes, too. Bit too laid back to be a good MC, though, especially in the face of some of the shit. Our boy has plot armor, and knows the hell out of it.
Olivia is the epitome of the trope this manga is Rick rolling, but she's less objectionable a Mary Sue than many. Plus, she does have a few real struggles. So that's fun. It'd be a lot more satisfying to see her grow out of her purely love interest personality, but at least she isn't a wet wad of cringe and codependency like a lot of female leads are.
Angelica is probably the most nuanced and genuine character here, with a believable arc from discarded-but-emotionally-invested 'villainess' to kind of a badass. She loses some points for stepping back too often and functioning more as an emotional support than anything, but there's nothing as artificial as I expected.
Marie...hoo, boy. You KNOW the author was picturing someone he knows well in his head with her. Just a nasty, spiteful little creature, selfish and self centered to the point of what I would call absurdity if I didn't see so many women just as toxic in real life. She's fun to hate. Maybe she'll become more interesting than that at some point, but the fact that she's kind of unrepentant about being awful, or at least doesn't accept responsibility for the actions that arise out of her awfulness, makes that unlikely. Kind of feel like there's a weird kinda-sorta-if-you-squint-and-take-LSD-pseudo-incest vibe in the making.
Call it 7/10, maybe 7.5/10 if pushed.
