the concept of monster being a hidden gem LOL
And yet! And STILL!!! Lol
I'm out of read, do you have any recommendations even out of mangago that i can read for free ? Your hidden gems ?
I read A LOT so some very niche stuff
(i struggle to read if i don't like the art saddly so if the art is too different i might not enjoy it)
