Been reading it lately, and it helps reduce my scrolling time. I've hardly read any, so you can recommend really popular stuff, too.
I've read Vagabond, 20th Century Boys, Claymore (years ago), and some berserk. I just finished reading Teppu, which I thought was an interesting subversion of a lot of anime tropes. I also liked that it was a short run (only 8 volumes). I guess I like seinen, but I've also enjoyed josei like She Loves to Cook, and She Loves to Eat.
Anyway, no shonen please. Hard mode: please nothing about high school
I will always take the opportunity to recommend How Do We Relationship?. It's got some of the most realistic depiction of relationships I've seen in japanese media. Keep reading after the heartbreaks; that's when it gets really good.
Idk why it's labelled shonen; people I know who've enjoyed it the most are women. Ig shonen's become a more abstract label these days.
YESSS this shit is so fucking good oh my god
Fr, I have yet to find any other romance anime/manga that's just so... real. Most are too trope-y or tragic.
