The Hidden Heir Billionaire System

"Pack your things and get out! You’re no longer part of the Moonlight Pack." Alpha Robin's cold, merciless command shattered Clara Edelweiss’s heart, leaving an invisible wound that ran deep. Betrayed and rejected by the one she once loved, Clara finds herself cast aside as Alpha Robin returns to his ex, choosing her as his mate and leaving Clara with nothing but the bitter taste of betrayal. Just as her world seems beyond repair, Alpha Daniel—her childhood friend and the only one who ever truly understood her—steps in to help her heal. With his support, Clara begins to piece her life back together, only to discover a miracle: she is carrying a child, despite once being told she could never have one. But when Alpha Robin learns of Clara’s pregnancy, he’s determined to reclaim her and their unborn child, igniting a storm of jealousy in Susan, his chosen mate. Caught in a deadly web of envy, danger, and manipulation, Clara is thrust into a battle for survival—and forced to confront her own conflicting desires for love, revenge, and redemption. In a world where loyalty is as fragile as a promise, Clara must decide: Will she surrender to the past or fight for the future she never thought possible?

As a male Omega, stepping onto the ice was never supposed to be my dream. Hockey belonged to Alphas—strong, dominant, born to conquer both the rink and everyone on it. Omegas like me were meant to stay hidden, protected, controlled. But hiding had never been enough. The World Hockey Academy was the only place powerful enough to shield my identity, the only place my adoptive father—its Dean—believed I could survive. To the public, it was an elite sports academy. To those like me, it was a prison disguised as opportunity. To them… it was Alpha Academy. From the moment I arrived, I swallowed suppressants like oxygen. Every breath had to be measured. Every movement controlled. A single slip—one flare of Omega scent—and I would be exposed. I had to skate like an Alpha. Fight like an Alpha. Bleed like one. On the ice, weakness wasn’t forgiven. That was when I noticed him. The strongest Alpha in the academy. The storm everyone feared. His presence alone made my knees weaken, my instincts scream in panic and hunger all at once. His golden eyes tracked me every time I touched the puck, sharp and suspicious, as if he already sensed something was wrong. During practice, we crashed into each other. The impact sent us both sprawling across the ice—but it was his hand gripping my jersey, his scent crashing over me, that shattered my control. My suppressants burned uselessly in my veins. His lips curved slowly, dangerously, as he leaned close enough for his breath to brush my ear. “Funny,” he murmured, voice low and certain. “For an Alpha… you smell like prey.” My heart slammed against my ribs. If he figured it out, everything would end. And yet— my Omega instincts whispered something far worse. I wanted him closer.

My love story with my Don husband was once the model relationship for couples all across Edale. But after his sudden death, the notary informed me that I was not the first in line to inherit his estate. I froze. Christian Fuzio was an only child. His parents had long passed away. We had no children. If I wasn't the first in line, then who was? That was when the boy walked in. His face was a perfect copy of Zoe Sgotti, Christian's assistant. The boy crossed his arms and sneered. "Mrs. Fuzio, the person my father loved most in his life was my mother. Of course, most of the inheritance belongs to us." Rae… Ray… Only then did I realize that the name he had whispered on his deathbed was never mine. I lunged forward to question Ray, but he shoved me into the traffic. The moment my head slammed against the ground, darkness swallowed everything. When I opened my eyes once more… I stared at my young, strong hands. Feeling the life that I had once lost growing inside me, I finally understood that I had been given another chance. Christian, this time, I no longer wanted your fake love. I would grant the three of you all the happiness that you wanted.
