Shiru's Manga

FL is sacrificed to a demon and tortured for 600 years (in the demon world). Later she's given a choice to just die or get revenge. She obviously chooses revenge and actually commits to it. It's kinda promising BUT it hard to keep reading it, I just want to finish it so I can move on. 20

He's OBSESSED with the FL. Ml saved her from her abusive father when none else did. From then on, she stayed at his place as a parrot "pet". I don't know how many more chapters there will be, but I'm at 29 and it looks like there isn't much story left

Kids FL abandoned the ML and now he's planning to have his revenge but can he really? Obviously, no. He's still in love with her. Btw, she had to marry an old dude (dead) and people think she poisoned him, probably the old dude's family bullied her.

This is really good! Enemies to lovers (to maybe enemies again). Ml's dad is having an affair with fl's mom, such a good start. Honestly it looks like fl's mom was groomed... so I don't hate her as much as I despise ml's dad. Anyway, they are both horrible.

I ducking finally found it

Living in the constant shadow of your dead sister falling in love with a womaniser the plot is actually good tho. She needs to become a priestess (because of her family) and ends up asking for help to someone she would have never imagined. Also she wants to break off her engagemen.
