The Alpha Refused to Claim Me, but the Alpha King Did

The seer foretells that I will mate with an Alpha and give birth to the strongest heir. Because of this, I am arranged to be mates with the Alpha heir, Chad Gibson, since I was a child. And from then on, I am groomed to become a Luna. I devote my entire youth to bleeding, fighting, and enduring it all. Every smile, every step, and every breath is for the sole purpose of becoming the perfect Luna. And yet, what do I receive in the end? On the day of the marking ceremony, Chad carries in an expecting Rogue with Omega bloodline, Yelena Lockhart. He then publicly declares that during a hunt, he accidentally consumed a lustbane and bred with Yelena. Thus, he must take responsibility and make her his future Luna. Seeing the unshakable resolve on his face, I ask in a trembling voice, "What about me? What am I supposed to do?" Without a moment's hesitation, he replies, "Tessa, because of that false prophecy, you have stolen the future Luna's place and enjoyed privileges that were never yours for long enough. Now, you must step aside. "But don't worry, I won't cast you out. As long as you keep serving Yelena as her maid in atonement, you may still stay by my side." The world falls into dead silence, and the stares of the pack weigh on me like a mountain. I neither scream nor beg. Instead, I simply remove my veil and return the ring that symbolizes the future Luna. Later, when Yelena gives birth, the pup turns out to be of Omega bloodline. Only then does Chad realize the prophecy is true, that I alone can bear the Alpha heir destined to lead. But when Chad finally regrets everything and begs me to come back, it is already too late. I have already accepted the Alpha King's proposal and no longer belong to Chad.
