People either hate or love this, you can decide for yourself if it's good or nah (it's kind of like Chainsaw Man a bit) - https://www.mangago.me/read-manga/drama_queen/

Okay, exceptions to those that is currently growing like chainsaw man, dandadan, and kaiju no.8 etc. I know stuff like gokuragai that is definitely gonna blow up in the future.
So what mangas would you personally recs right now that have 50 chapters and below that would deserve the hype?
