Also, I might be wrong but I think I remember people talking about the recommendation above (Red Mansion) being toxic so please check the comments!

Hello I just wanted some recs for really angsty manga/manhwa but I would prefer if there was no rape.. or toxic gaslighting Yada yada if it is there then mild ig lol.. ugh I really don't know how to put this into words.. anyways stories where the MCs suffer cuz of each other or stories where MCs have a backbone. Even straight stories are fine but I don't want any smut in straight stories lol
