He Said His Adopted Sister Was "Just a Child"

My fated mate, Alpha Felix, had always put his adoptive sister, Serena, first. Whenever danger struck, his first instinct was always to pull her into his arms. The night our pack was attacked by rogues, he smashed through three doors just to carry Serena out of her room first. Only after making sure she was safe did he remember I was still trapped in the thick smoke. He then sent someone to find me. That incident left a bad burn scar on my shoulder. For the very first time, I forced him to choose between me and Serena. He looked at me in confusion. "Nova, Serena is just my sister. Besides, she is much weaker. Why are you competing with her?" "I swear to you, I'll treat you both equally from now on, okay?" Yet, on the day we were supposed to step onto the altar to take our vows, Serena followed us all the way to the Moon Goddess statue. Her first words were: "Brother, this is your first time taking a vow before the Moon Goddess. Shouldn't I go first?" Felix chuckled, ruffled her hair, and told her this time was different. But Serena refused to let it go. She tugged at his sleeve and begged him over and over. I watched the resolve in Felix's eyes crumble. Just as he was about to turn around to comfort me, I simply laughed. Our bond of seven years was meaningless. Without waiting for him to speak, I pulled the pack token out of my bag and shoved it into his hand. I lifted my chin toward the altar. "Go ahead."
