Historical :v

Betrayed by her trusted cousin and her fiance, she wishes for revenge for her dead family and lives a 2nd life (ML gives up his immortality for her wish).

FL lives as a male to act as an heir for her father. She befriends the villainess and the ML, and they're practically besties. wFL gets transported to the world and wML acts like his body is being manipulated (to act as he did in the books) but he tries to fight it

FL regrets being petty towards ML, her family and ML dies. 2nd life treats ML better and wants revenge

FL dies from giving birth. ML was always cold to FL, ML regrets and wishes that time could go back. ML and FL have 1st life memories. FL cares most about her child and so goes ahead with the marriage so she could get him back and this time protect him herself. End of S1 FL decides to divorce ML. S2 gradually they repair their relationship whilst protecting their son.

FL is hired to take care of the ML's kids (not actually his). She only plans to do it until the wFL appears. ML falls for her and hopes she stays forever. The ML's family has a 'madness' disease that runs in their family where they are only sated with the sight of blood.

FL transmigrates into an extra who got killed by the villain - said villain threatens her into a fake marriage with him for show but falls for her. FL is still scared of him (attracted but doesn't trust him).

FL transmigrates into the wFL's younger sister who dies from the ML (assuming he lost control of the calamity sealed inside him). FL is a witch and agrees to help ML try to get rid of the calamity in him. ML learns to cherish and trust the FL instead of keeping her in a cage to try and protect her.

FL drinks a potion thinking it would turn back time after she gets stabbed but instead turns her into a child. ML finds her and identifies her as his mate but then wakes up and he denies it (coz ya no she a child now and also the pheromone disappeared).

FL keeps living the same life after dying on her 25th birthday. She decides to befriend the rebels and help them get rid of the imperial family. FL is dying but isn't afraid; it seems as if she wants eternal rest but is currently enjoying being with everyone.

FL dies in the arms of the one she loves. Wakes up back in time, gets proposed to by ML (because he got a note from his future self that she is the one he will love) and her uncle and aunt leave her home.
