I'd prefer school life genres, Highschool/College

I consider mangas as hidden gems like:

—She's Likely Aiming for my Older Brother

—(The image)

—Artemis Under The Same Roof

—Haimiya-Senpai is Scary But Cute (Although honestly this is popular nowadays)

—I Want to End This Love Game (Popular now, and it got an anime)

Obvious non hidden gems, are like KaoruHana (although it was on the first releases), The Mortifying Ideal of Being Seen. Basically anything good that isn't really hidden per se
