"I'm not yours!" I snap, my eyes narrowing into slits as I glare at him. A wicked grin curls on his lips. "Oh, but you are, little deer. How can you even begin to deny it?" He leans in closer, his breath hot against my neck as he drags his nose along my skin, inhaling deeply. "You let me touch you. Now, you. Are. Mine." I shake my head vigorously, my voice trembling as I stammer, "I... I wasn't awake. I didn't know it was you. I thought it was him!" The words spill out, more an attempt to convince myself than to sway him. His dark, sinister laugh reverberates as he presses closer, pinning me against the wall, his body a cage around mine. "Yet your eyes were fixed on his face, weren't they, little deer? Even as you came so hard around my fingers." He's right.

But what she doesn't know is that Dante, the man she trusted, is the very stalker who has been obsessing over her for years. And now, with her so close, his twisted desires are becoming impossible to resist.

Evonne Shannon was a poor student mother sponsored. She was also the crush I had been courting for a long time. Wanting to allow her to shine, I gave up my place in the piano competition for her. However, she glared at me with disdain for deciding this on my own. She then instantly turned around and handed the registration form to her boyfriend, Angelo Zambrano, and said, "Ange, only you deserve this competition." Evonne liked sports cars, so I begged my mother to buy her a limited-edition McLaren supercar. But in return, Evonne mocked me and called me shallow. "Don't think I'll accept you just because I'm accepting the car, Chase Shannon. You've never understood me." With my help, Evonne got to put on a facade of a mysterious billionaire's daughter. But the moment she got money from me, she turned around and went on a romantic getaway with Angelo. I thought of Evonne as my everything and even asked my mother to arrange for her to join the family company. Within half a year, she was promoted to a core team member. She then conspired with Angelo to drain the company dry and even forced me to my death. "What else can you do besides insult me with money and a materialistic lifestyle, Chase? You're the most disgusting obstacle on my path to success. Only when you're dead can I marry Ange," she declared. I was heartbroken when I heard this, and that was when Evonne pushed me off the sidewalk and into traffic. Immediately after that incident, I was reincarnated to the day I bought Evonne a piano. She was glaring at me with disdain. "If you don't want to buy it, just say so. There's no need to humiliate me like this." I let out a dismissive scoff. "Am I the one who's humiliating you, or are you the shameless one? You beg for food but complain that it's cold. You're worse than those stray dogs on the streets. At least they show gratitude after getting scraps."

I'd had a crush on my brother's best friend, Ethan—the most powerful Alpha of our Northern Territory—since I was twelve years old. When I was fifteen, I boldly confessed my feelings to him. He laughed and patted my head, casually promising, "When you turn eighteen and shift, if you're my mate, I'll mark you." That offhand promise became my greatest hope for three years. I spent every day waiting for my wolf to awaken, praying to the Moon Goddess that she would designate us as mates. But on the night of my eighteenth birthday, after my wolf first awakened, I was shocked to discover that Ethan truly was my mate! Ignoring the intense shifting pain coursing through my body, I immediately shifted into my wolf form and ran toward Ethan's training grounds. I clutched the gift I'd prepared long ago, but instead heard Ethan urgently confessing to his Omega assistant Victoria: "Who would be stupid enough to actually care about a true mate? The bond between her and me is just the Moon Goddess's mistake. I only love you. I'll only mark you as my Luna." The words hit me like silver bullets to the chest. My wolf whimpered in pain, the mate bond burning like acid in my veins. I stood frozen behind the trees, watching the man I'd loved for six years dismiss our sacred connection as if it meant nothing. Later, Ethan introduced Victoria as his "fiancée." When Victoria demanded that I publicly bless their marking ceremony, Ethan remained completely indifferent to my humiliation. "Sylvia should give us her blessing," Victoria announced at the pack meeting, her voice sweet as poison. "After all, she's been like a little sister to Ethan all these years." Every wolf in the room could smell my distress. But Ethan said nothing, refusing to even look at me. When rogue wolves attacked our territory and I was surrounded, Ethan didn't hesitate to scoop up Victoria—who had only a tiny scratch on her finger—and carry her away to find the pack healer. He left me bleeding and alone, silver claws ha
