Framed by the alpha's true daughter, my family regrets very much

As I was about to step back, Jade suddenly grabbed my wrist. "You should understand your place by now, right? It's better not to think about competing with me. If you do, I'll make sure you regret it." I let out a cold laugh. "All this effort to compete with me for these things? Then why did you even let me come back? I've already said I'd leave." The pressure in Jade's grip increased gradually. "What if you can't make up your mind and show up again to steal from me?" "Sis, I want you to fully understand-this family, and Alpha Sabastian's heart, have no place for you anymore." At that moment, hurried footsteps echoed from outside, and I instinctively looked up. But as soon as Jade saw the figure approaching, she released my wrist and tumbled down the stairs. "Jade!" Alpha Sabastian had just entered the door and witnessed the scene. He rushed to the bottom of the stairs, lifting Jade in his arms. "Alpha Sabastian, don't blame my sister. It's my fault I lost my balance and fell." With that weak sentence, Jade passed out in his arms. I stood there, conflicted, wanting to explain myself, but my words failed to leave my lips. "Rona, are you out of your mind? What did Jade do to you for you to treat her like this?" Alpha Sabastian called for the pack doctor. After hanging up, he glared at me, seething with anger. His face twisted with disappointment. "If anything happens to Jade, your parents will definitely send you back to prison!" They could treat me however they liked, but I couldn't bear the thought of returning to that place. "I didn't push her. She wanted to prove she was more important to you, so she did this herself." "Sabastian, we grew up together. You know I would never do such a thing, right?" But the Alpha Sabastian who once promised to protect me forever, now simply turned his gaze away coldly. "I don't know. All I saw was you push Jade down." Hearing that, the last shred of hope I had shattered completely. Jade, still lying on the ground, slowly opened her eyes. After a brief moment of eye contact, her lips curled into a faint smile. Even from this distance, I could clearly read her lips. She silently mouthed, "You lost." I turned to leave for my room, but Jade called me again. "Sis, my head hurts. Would you come with me to the pack medical center?" Reluctantly, I followed them. On the way, Alpha Sabastian clutched Jade's hand tightly, his eyes filled with tenderness. He kept asking if she was okay, constantly checking on her, as though fearing any harm would come to her. In that haze, memories of the three years I spent in prison resurfaced. Back then, I had asked Sabastian for help, but he merely told me, "Even if you get locked up, you won't suffer." "Rona, you've had Jade's good life for so many years. Stop being so dramatic now." Three years in prison wasn't considered suffering, but Jade falling just once had him so frazzled. My chest felt tight, suffocating, but I forced myself to remain calm, putting on an indifferent face. When we arrived at the pack medical center, Sabastian was pacing outside, restless. Even when the doctor assured him Jade would be fine, he still couldn't relax.
