Hidden Vengeance: My Childhood Friend's Fiancée is His Victim's Sister and My Sworn Enemy

"On my birthday party, Lucas, my childhood friend and fiancé, brought a girl with him. He said she was strong-willed, resilient, and radiant - his true soulmate. And that a proud and aloof rich young lady like me could never be his future wife. The arrival of this girl disrupted my birthday celebration. But then I discovered she was the sister of a boy Lucas had bullied and disabled in high school. 1 I had been told by Lucas's friends that he'd been getting close to a girl recently. But I never expected him to bring her to my birthday party. Under the fiery glare of Mr. Thompson, Lucas still said those words: "This is my girlfriend, and my future wife." The girl he was holding hands with blushed, her eyes shy. She didn't seem to think there was anything wrong with crashing my birthday party. Mrs. Thompson's face clouded over. Catching sight of my mother's darkened expression, Mrs. Thompson rushed forward and pulled Lucas aside. Lucas refused to let go of the girl's hand, so they were both dragged to a corner of the banquet hall. Mrs. Thompson scolded in a low voice: "What do you think you're doing?" Lucas glanced at me watching the show and said without any courtesy: "Lily is kind and strong. The moment I saw her, I knew she was my true love. I can't cater to a snobbish heiress like Rachel."

Understanding my implication, Lily's face turned pale. Lucas reached out and shielded Lily behind him: "Rachel, I know you're angry that I broke our engagement, but Lily and I are truly in love. Nothing you say will change my mind." I asked him: "Are you done?" Lucas stared blankly for a moment, then nodded. "If you're done, then I'm going to cut the cake." I turned and walked to my mother's side. Mrs. Wilson, our housekeeper, pushed the cart with the cake closer to me. I picked up the knife, glanced at Lucas, smirked, and viciously cut the little figures on the cake in half. My parents' friends were tactful. Despite the drama that had just unfolded, they still said things like: "Your Rachel has grown into such a beauty. My nephew is still single, why don't we have dinner together someday?" As if I had never had Lucas as a fiancé, they dissolved the awkwardness of the scene Lucas had created with just a few words. I smiled slightly, occasionally responding with a word or two. In my peripheral vision, I saw Mr. Thompson angrily slap Lucas. The sound of the slap was so loud that it dr...
