Why Does The Protagonist In 'Day 21' Make That Choice?

After I was caught in a dockside explosion, I was bound to a Survival Program. It gave me twenty-five years and four designated targets. If even one target’s Love Score or bond score reached 100%, I could wake up in my real world. But I failed all four. Because every target I tried to reach eventually turned toward Sophia Lane, the heroine of this world. They called my pain a performance. They called my tears manipulation. They said I was only pretending to break down so they would choose me over Sophia. But if they never loved me, why did they lose control when my mission failed and I chose to leave this world for good?

My fiance is the best Neuro Healer among the werewolves. His first love is his little stepsister, who once took a fatal silver arrow for him. Now, her old condition has flared up, and she has a fatal silver venom disease. She only has 21 days left to live. In order to stay with her in her final days, he pours his newly developed "Memory Lock Potion" into me to eliminate all my memories of him by force. He says, "It's just 21 days. Once she's gone, I'll feed you the antidote myself, and you'll remember me again." In those 21 days, he holds a grand bonding ceremony for his stepsister, dances with her during the Moon Goddess Festival, and makes an oath swearing that they will become mates again in their next life. Finally, he sends her off. After 21 days, the potion wears off, and he kneels in the rain with tears and blood all over his face. He asks hoarsely in an accusing tone, "The potion only lasts for 21 days… why have you forgotten me completely?" I just look up impassively at him. "Sorry, but who are you?"

Everyone in Oceanton knew that mob boss Jared Pierce was deeply in love with me. No one feared my disappearance more than he did. Even if bullets were raining down on him, he'd still find a way to contact me, just to make sure I felt safe. But on the night before our wedding, he didn't come home. When he finally returned, he dropped to his knees, a bruised and weakened woman cradled in his arms. "Rosalia! Melody took the drug just to save me! I can't just watch her die! So I had no choice but to sleep with her." Terrified that I wouldn't forgive him, Jared drew six wounds into his arm. Blood soaked through his shirt in an instant. As soon as the wedding banquet ended, I heard his men chuckling and teasing. "The boss didn't even take off his wedding outfit before rushing to see Melody. Just how seductive is his lover?" Jared’s low, sultry voice followed. "Last time I stayed with her, I didn’t come back for three days and nights. Take a guess." In shock and despair, I called out the system. "I want to leave this world!" The system's cold voice replied, "After your exit, this world will erase all traces of your existence. Counting down… Seven days."

My mate, David Hayes, who is the Alpha, has been cold to me ever since he claimed me as Luna of the pack. He assumes that I gave him a dose of pheromones under the full moon. That was why I got the chance to mate with him and ended up being pregnant so quickly. So, as an Alpha, and for the sake of his reputation, he decides to mark me. That is how I became his "mystery Luna". The pack only knows that he has a Luna, but no one knows it's me. When I gave birth to our pup the next year, he showed no interest in the slightest. When a lupine maid brings the newborn to him, he glances at the pup with disgust and turns away. "Let's hope he's nothing like his mother—scheming, manipulative, and a disgrace to the pack!" I lie in bed, weak and exhausted, but the tears won't stop. … Today, David's childhood friend, Sophia Sinclair, returned to the pack. The moment he heard the news, he lit up with excitement. That night, after coming back from Sophia's place, drunk out of his mind, he pulled our pup into his arms. My son, Joseph Hayes, was over the moon. He snuggled closer to him and whispered to me, "Mom, he hugged me on his own… Does that mean he accepts me now?" I held him tight, tears stinging my eyes. "His mate has come back. We're leaving the pack." What he didn't know was that the healer had already told me I have Wolf Spirit Degeneration, which leaves me only three days to live. Before I die, I'll take Joseph to my parents, where he'll be loved and cared for, and not hated and abandoned by his own father. In three days, David will never see me or our pup again—and for the rest of his life.

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.

The apocalypse has arrived. I carry multiple special abilities and am humanity's hope. However, my wife tears those powers out of me for the sake of her true love. I'm in unbearable pain. I beg her to stop, telling her I'll die. But she doesn't care at all. "Why are you so selfish? You have so many abilities and won't even give one to Ed. Stop being so dramatic. Why do you get to be the hero while my Ed stays an ordinary person?" What she doesn't know is that each special ability is like a heart—take it away, and the person dies.
