I've been binge watching anime recently but I've never read manga before. I like stuff with drama, relationships, sci-fi and all forms of mind-fuckery but I'm open to pretty much anything that isn't isekai or shounen. Could I get some 'beginner' recommendations? I'm especially looking for stuff that is complete, not ongoing and has a decent ending/provides closure.

Also I sometimes see manga and anime infographics posted but I've never saved them. Feel free to dump those if you have them handy.
