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.

FL has some sort of power, might be a vamp as she drinks blood. Her only childhood friend believed in her and trusted in her but he was killed by the village as they saw his bite mark and staked him. FL now in a high school (seems like there are 2 campuses, one for weres, one for vamps).

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).
