Why Does The Protagonist Change In 'Six Months Later'?

The world plunged into a new Ice Age. As the frozen apocalypse spread, 95% of humanity perished. In his first timeline, Cyrus Knovell's kindness cost him everything. The people he had helped betrayed him and left him for dead. Fate, however, granted him a second chance. He awakened one month before the world froze, gaining a dimensional ability that let him store anything without limit. Now he hoarded supplies by the billions and built a fortress no one could breach. While others shivered, starved, and traded their dignity for a morsel, Cyrus lived in comfort. The desperate came begging. The manipulative vixen: "Cyrus, let me into your shelter, and I'll be your girlfriend, okay?" The spoiled rich heir: "Cyrus, I'll give you all my money for just one meal!" The greedy neighbors: "Cyrus, you shouldn't be so selfish. You should share your supplies with us!" Cyrus remembered their betrayals. Lounging in his steel fortress and savoring his private paradise, he sneered, "Your survival has nothing to do with me. I'd rather feed the dogs than feed you."

The end of the world was upon us, but there weren't enough spots for evacuation. The roars of the zombies echoed in my ears as my fiancé, Oliver, gritted his teeth and pulled me onto the rescue vehicle—securing the last available seat. I arrived safely at the survivor base. Lina, his first love, did not. The zombies tore her apart. Oliver still went through with our marriage, but I never expected that he had only done so to make me suffer. In his eyes, I was the one who had killed Lina. If she had to endure such agony, then I should, too. For five years, he hated me. My life was worse than that of a stray dog scavenging for food on the street. On the day my divorce was finalized, he kidnapped me, dragged me into the wilderness, and wrapped his fingers around my throat. Then, he threw us both into the swarm of the undead. When I opened my eyes again, I was somehow reborn on the day the apocalypse began. The rescue team was shouting impatiently, "One more! We have room for one more—hurry!" I turned to Oliver, watching his hesitation. Then, with a quiet smile, I took a step back and let someone else have the last seat.

In October 2025, an explosion occurs at a remote lab. An unidentified substance is leaked, and the virus makes people go insane. Anyone who is bitten by these rabid creatures becomes one of them. It's like the zombies people see in movies and video games. On the first day of the explosion, my five-year-old, Joyce Fairfield, is still at kindergarten. I risk my life to hurry there, but I can't even find her corpse when I arrive. I can only look at the surveillance footage to see her face, which is ashen with fear. I also see her mouth, "Mommy!" 15 days after the explosion, I finally traverse the city and get to my mother's home. However, all that welcomes me is a destroyed apartment and blood everywhere. 20 days after the explosion, my husband, Emmett Fairfield, calls me one last time from his office, which zombies have surrounded. He tells me not to leave the house. Less than a month after the apocalypse arrives, I lose all my family. I'm alone as I struggle to survive in this dead world. The spread of the virus triggers chaos in mankind. I exchange all my supplies to save a neighboring couple from bandits, leading them to safety in a secure zone where they can live stable lives. However, my kindness is not repaid. Three years after the explosion, the secure zone is under siege by a wave of zombies. As we retreat, my neighbors shove me underneath a car so I'll distract the zombies. Then, they make a run for it and get away. Trusted neighbors betray me. As the zombies eat away at me, I can feel death looming. All I want is to see my family again. Now, I've been reborn. I have six hours before the zombie apocalypse breaks out.
