Which Thors Fanfics Depict Sibling Rivalry Turning Into Deep Emotional Bonds?

On my eighteenth birthday, the High King summoned the heirs of the four great clans—the Vampires, the Werewolves, the High Serpent Clan, and the Merfolk. He laid their portraits before me and said, "Choose one to be your bondmate." I did not hesitate. I pointed to Damon—the werewolf with no noble bloodline, born in a forgotten corner of the realm. The entire court erupted in disbelief. Everyone knew who I used to love. Alpha Iris—the heir of the most powerful Lycan bloodline. For seven years, I chased him with blind devotion. No matter how harshly he treated me, I never gave up. I confessed to him over and over, sometimes right in the royal court. I even performed a blood-binding ritual—slitting my wrist—to earn the right to marry him. In my previous life, I got what I wanted—I married him and we performed the mate bonding ceremony. With that union, he inherited the High King's resources and rose to become the ruler of all four clans. However, what I did not expect was that after our wedding, he turned around and marked my adoptive sister. My parents were furious and sent her away. From that day on, Iris hated me with a vengeance. He surrounded himself with women who all looked eerily like her. One by one, they came—each more vicious than the last. With his silent approval, they tore me down, piece by piece, until I was nothing more than a joke—no longer the queen I once was. The suffering pushed me into severe depression. Only suppressants keep my wolf form from spiraling out of control. Until one day, my medication was replaced with a slow-acting poison. He was the one who did it. I died alone, locked away in the cold palace, a child still growing inside me. However, fate gave me another chance. In this life, I would not make the same mistake. When the High King once again asked me to choose a partner for the marriage alliance, I chose Damon—the one no one ever noticed—without even blinking. I thought I was finally free of the past. However, the moment the engagement was announced… Alpha Iris lost his mind.
