How Does The Protagonist In 'Reincarnated In Mushoku Tensei Realistically Overpowered' Differ From Rudeus?

Elina thought she had hit rock bottom. She lost her job. Her therapy session dredged up memories of the ex-boyfriend who stalked and traumatized her. The only thing she had left to look forward to was the finale of her favorite fantasy series, Moonbound Faith. Then the show ended. The heroes won. The villain died. Everyone got their happily-ever-after. That same night, a knock at her door shatters what little peace she has left. Her ex is standing outside. The man who was supposed to be in prison. Forced to flee into a storm, Elina runs until she reaches the edge of a cliff with nowhere left to go. Faced with a choice between death and returning to the man who destroyed her life, she jumps. But instead of dying, she wakes up inside Moonbound Faith. Not as the heroine. Not as a side character. But as Luna—the infamous villainess whose tragic death she celebrated only hours before. Determined to survive, Elina plans to use her knowledge of the story to change her fate. But everything she thought she knew begins to unravel when a small boy tugs on her sleeve and calls her one word: “Mom.” The original story never mentioned a child. And when Elina uncovers the truth behind his existence, she realizes something terrifying. The villainess was never the villain. The story lied. And the ending she remembers may not be the ending waiting for her at all.

On the day I return to my home to reunite with my actual family, Melanie Stewart, the fake heiress, shows up in front of me. Her neck is completely riddled with hickeys. Instantly, countless live comments appear in the air around me. "Poor Yvonne! She thought she could start living a comfortable and lavish life now that she had been accepted by her actual family. Little does she know that Melanie has already formed a pact with the transfer system!" "Melanie is a loose woman by nature, and she loves sleeping with countless men. After getting bound to the system, the children she gets pregnant with will be transferred into Yvonne's womb instead." "Yvonne will proceed to give birth to dozens of bastard children, thus humiliating her family to no end. She ends up getting cast out of her family by her own parents!" "The truth is, there's a solution to this situation. Yvonne can just remove her uterus so that the system won't work at all. Alas, she doesn't know about that." I stop in my tracks at that moment. In my previous life, I had believed the live comments. As such, I traveled to a hospital to get my uterus removed overnight. But the next day, Melanie blew the whistle on me to my parents. She claimed that I wanted to get rid of my uterus in order to cut down the risks completely for the sake of having as much fun as I wanted with other men. My parents were completely disappointed in me. My fiance refused to enter a marriage alliance with me, a woman who could no longer give birth, as well. In the end, I died from a post-surgical infection. However, Melanie obtained everything that was supposed to be mine, to begin with. That was how she became successful in life. When I open my eyes again, I realize I've returned to the day I'm bound to reunite with my family.
