The Ivanovas and the Vitales are well-known aristocratic families who have maintained everlasting friendship through generations. My name is Anastasia Ivanova. I have been the daughter of the Ivanovas for twenty years, only to discover just now that I was switched at birth. When I was swept out of the Ivanova’s mansion like rubbish, Lorenzo, the youngest son of the Vitale family, firmly picked me up in spite of all objections. Lorenzo always acted cold and distant toward me. I didn’t know why he came to take me into his car at that time. He whispered in my ear again and again, ‌"I’ve wanted you for a long time."‌ He pinned me against the leather seat, making me cry until my voice was hoarse. At that moment, I finally understood his coldness over the years was not indifference but restraint. Soon after, Lorenzo overrode all objections to marry me. His parents were vehemently against me, but Lorenzo directly stripped them of power and became the youngest godfather. Scarlett Montgomery tried to stop us from getting married, but Lorenzo canceled all her credit cards and threatened to send her away. I thought we would have a happy life. Three days before our wedding ceremony, he planned to send me abroad, claiming enemies might retaliate. But, I accidentally overheard him talking to Scarlett in the hallway at night. "Thank goodness. You tricked her into leaving until after I give birth. You’re so good to me!"‌ He kissed her cheek, ‌"I don’t want Anastasia know our affair. You must keep it secret."‌ Their dialogue made me devastated. But I didn’t confront him immediately. Instead, I quietly completed my immigration paperwork as a way to make a clean break with him.

After his first love died, Oscar hated me for ten years. I tried everything to soften him. Nothing worked. "If you really want to please me, go die." The words cut deep. But when the riot came, he threw himself in front of me and was hacked down where he stood. He stared at me as he bled out. "If only… my fated mate hadn't been you." At his funeral, his parents wept. "We should have let him be with Catherine. We forced him to marry her, all because of that damn prophecy." Windvale Pack lived by prophecy. Years ago, the Seer had foretold that if Oscar didn't take his fated mate as his bond-mate, disaster would fall on the pack. I was that fated mate. But now, everyone wished I never had been. Even me. I was driven from the funeral, hollow. Then the Moon Goddess descended. She offered me a chance—ten years back—on two conditions. I would not become Oscar's mate. I would prevent Catherine's death. I said yes without thinking.

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.
