I want sth to read

I want some recommendations... I am kinda picky when it comes to manga, nothing yuri, ecchi or yaoi
I've read jjk, hell's paradise, firefly wedding, yakuza fiancee, juujika and a lot of manhwas like sl, omniscient reader's viewpoint and others.
I'm not looking for sth with (only) romance, i want sth interesting and with maybe over 70+ chapters and completed. Tragedy or gore is also welcomed.
