Mia

Mia (born in the late 1970's) is the daughter of Carol Helen (Melissa in her previous life), the niece of Helen and Kara, the stepdaughter of Judy, the step-niece of Adrianne, the stepsister of Eleanor and Zara, the step-aunt of Nicole, the mother of Doutzen, the stepmother of Leila and the lover of Dominic (who she also had children with (Sandy being the oldest of them)) (during the brief time they were together).

Before the reveal that Melissa was Carol Helen in her previous life (and Melissa remembering her previous life), Melissa and Mia had been in a relationship for years, first randomly meeting not long after each of them got pregnant (Melissa with Leila and Mia with Doutzen), which lead to them to dating and moving in together, so they could more easily raise Leila and Doutzen together (Melissa becoming the official other parent (stepmom) to Doutzen and Mia likewise becoming the official other parent (stepmom) for Leila), which lasted until the truth came out and Melissa remembered her previous life (though Melissa still remained the official other parent (stepmom) to Doutzen and so did Mia for Leila).

While they still loved each other romantically even after the reveal and Melissa remembering her previous life, they knew that in the end, it wouldn't work even if they wanted to, so they break up.

Sometime after Mia and Dominic break up, as Melissa and Mia still love each other very much, they evantually end up back together (and are still together in 2030), not caring about Melissa being Carol Helen in her previous life, as they see Melissa being her own person instead of being just a reincarnation of Carol Helen.

They also still make love to each other from time to time; though Zara does sometimes, very rarely, join in, making it a threesome (which stops happening sometime before 2030); and if Mia and Melissa want a threesome that doesn't involve Zara and that happens far more often, after she turned 18, Sandy started to join them instead (which still happens in 2030); evantually only Sandy joins them and often; it ends up happening so often in-fact, that the three of them could be though as a polyamory and by 2030, all three of them are married and call each other their wife's (example; Mia is the wife of Melissa and Sandy); also, they have kids too (made possible thanks to magic).
