Also i saw you have The Law of Raising a Wolf in your want to read so imma just tell you to not bother yourself reading that horrendous manhua. The mc puts up with the ml abuse towards him and the ml basically "cheats" on him (i dont remember if he dated mc when he dates girls but ml still treats mc horribly). the male lead is a toxic asshole and the main character is weak and most likely forgives him in the end. I ended up dropping it. it'll just piss you off.
oh also read https://www.mangago.zone/read-manga/serial_justice/
its about a girl murdering child abusers and a detective helps her. its literally my favorite manhwa so far.
tyyyy sm ヾ(❀╹◡╹)ﾉ~
