How A Realist Hero Rebuilt The Kingdom Manga Ending Explained?

[YOU HAVE TRANSMIGRATED INTO A VILLAINESS FATED TO DIE.] I was supposed to obsess over the Alpha King, scheme against the heroine, and meet my end at the execution block. Instead, I rewrote the story. I chose Pierre Ashbourne—the neglected second male lead I once pitied as a reader—and spent three years helping him rebuild his dying pack, believing I had finally changed my fate. Then he abandoned me at our mating ceremony for his first love, the heroine. Now, the system has given me only one way home, restore the original ending by pushing the heroine back into the arms of the ruthless Alpha King, Hades. But the more I try to complete the story, the more these leads are getting out of character! What should I do?

Evy was a simple-minded girl. If there's work she's there. Evy is a known workaholic.

I saved the current queen with my medical expertise and ability to save patients from the clutches of death itself. To fulfil my long-time wish, the queen intended to order that I was to marry the son of a marquess, Eldwin Gennings. However, I fell on my knees and begged her to let me marry a notoriously useless rich heir instead. The queen was shocked. After all, everyone in the Royal Capital knew that I had been in love with Eldwin since we were young. I had even said several times that I would not marry anyone but him. In my past life, I had indeed married Eldwin, just as I wished, but on the night of our wedding, he left me waiting alone in our bedroom. The next day, he married my half-sister as his second wife. I was bullied and framed by my half-sister. As a result, Eldwin cut my wrist tendons and damaged my arms permanently. In the end, my wounds got infected, and I died. When I opened my eyes again, time had rewound to the day the queen ordered me and Eldwin to be married. This time, when he found out that I wanted to marry someone else, he went mad and begged me to take him in.

After a car accident left me with amnesia, a woman claiming to be my girlfriend proposed to me in the most heartfelt way. Everyone around me said I'd been waiting for this moment for seven whole years and urged me to just say yes. In my past life, I nodded along without thinking twice. Her childhood best friend, who turned out to be the long-lost biological son of my parents, ended up going with them to Neller City—and completely leapfrogged into a whole new social class. As for me, I followed Estelle Camden back to her hometown and became just some ordinary guy from the countryside. Cooking, doing laundry, taking care of her bedridden father—I did it all, for thirty years straight. But Estelle left to find work in the city just a year after we got married, and she'd only come back once every few years. The money she sent was barely enough to keep a beggar going. It wasn't until I lay wasted away on my deathbed, barely clinging to life, that I finally saw the truth in her cold, calculating eyes. She let out a sigh of relief and confessed, "The couple who came looking for their child back then—they were your real parents. They're worth hundreds of millions. But you? You're so ordinary—what right did you have to that kind of life? So I gave the DNA test to Derek instead. "Derek is handsome and clever. He deserves the good life way more than you do." When she saw the rage burning in my eyes, she just gave a careless little smile. "You know, sometimes I actually felt guilty looking at you. But now, you're finally about to die—so I guess that's one less thing weighing on my conscience." Right after she said that, I coughed up a mouthful of blood and died, seething with regret. When I opened my eyes again, I was back in that hospital bed—and Estelle was asking me to marry her.

In a drought-ravaged apocalypse, I kept our entire apartment block alive with my “watermaker” ability. But when I grew weak, my neighbors shattered my limbs and turned me into a living water source. Later, when raiders stormed in, they dragged me out to take the blade for them, only to realize that even my severed arms could still produce water. So, they shouted about “saving humanity,” then shoved me into the crowd and fled in the chaos. People rushed forward one after another, tearing at my flesh. But I didn’t die. What was left of me fell into the hands of a monster, and I was subjected to inhuman torment day after day. Ten years later, when the apocalypse finally ended, that monster tossed me into an incinerator. Only then did I die. When I opened my eyes again, I had returned to the moment I first awakened my ability, just as my neighbor knocked on the door, begging for water.
