If you’re looking for BL, I did a hidden gems post too and got a few good ones. One was Bones and Petals (lots of chapters like 80 something but ongoing about a vampire.) it’s intense but really really good.
I’m also currently reading Unchanged Man and Chairman, Cut the Crap both pretty popular and so good I can’t stop raving about them. They’re totally different tho.
Wolf Pack
I actually dont know how popular this series is since i only discovered it recently but it left me in awe since i had never heard of it before

I've been super bored and I want to read something new that I usually wouldn't read, or maybe even find. It can be any genre (although I don't deal well with tragedies but whatever); it can be a manhwa, manhua, manga, or a webtoon. Genuinely just anything that you read and thought "holy shit, why isn't this more popular?".
