At the company's annual gala, the CEO announced that this year's top sales performer would receive a two-million-dollar year-end bonus. I was the top performer. However, my manager called me into his office the very next day and explained that the company was cutting costs and improving efficiency. As a result, my bonus had to be reduced. I initially assumed everyone's bonus was being cut. Then, I found out I was the only one getting shortchanged. Even worse, they handed my position to a useless coworker who could barely do the job. I understood everything immediately. 'So this is how it is. You're tossing me aside after you got what you wanted from me.' Fine. I stopped putting in any effort from that day forward. I clocked in, did the bare minimum, and watched the company slowly fall apart. Sales began to drop month after month. Even the major clients I had already secured began withdrawing their investments. That was when the CEO finally panicked. He showed up at my front door, begging me to fix things. I kicked the door open and looked down at him. "You think a garbage company like yours deserves my help?"

The HR manager slid a severance agreement across the table and said coldly, "You're fired." I froze. "Why?" Just one week ago, my boss had praised me in the company meeting and called me one of the team's most valuable people. The HR manager shrugged. "Ms. Lyttle, you're already 35. You don't have the energy of younger employees anymore, and you're not what you used to be. You no longer fit the company's future." I joined this company when I was 29. Over the past six years, I wrote countless lines of code and worked through more sleepless nights than I could remember. Every time the company faced a major system failure, I led the emergency response and saved it from catastrophic losses. And now they were telling me I was too old and too slow. I laughed in disbelief. "So you've already copied all my experience and skills into an AI, haven't you?" The HR manager paused for a moment before answering confidently, "AI never gets tired, never takes time off, and never asks for a raise. Once the company has an employee like that, why would we keep you?" I looked at her. "Are you sure the AI has learned everything I know?" She smiled. "Absolutely." The moment I heard that, I finally relaxed. Long ago, I had already hidden a trap inside my code to keep my skills from being copied. The moment their AI employee went live, the company would only have three days before everything fell apart.

On the day Clara forced me to sign the divorce papers, I got bound to a self-sabotaging system. The system commanded me to slap her hard and tell her to get lost. I trembled in fear because Clara was a ruthless person. If I dared to stop her from getting back together with the love of her life, she would utterly destroy me. But the system threatened me: "If you don't self-sabotage, you will die soon." Left with no choice, I slapped her. As soon as I hit her, I ran out of the house, terrified. The system then told me to smash a police car on the side of the road. I suspected the system wanted me dead. However, after I smashed the police car's side view mirror, I realized that the system was trying to sabotage someone else's life instead.

My father was a senior HR executive. He used KPIs to define my life. "Rank top ten in your grade, and I'll give you a B, with a bonus of 250 dollars. "Place in a state-level competition, and you'll get an A, with a bonus of 500. "If your SAT score hits Ivy-level, I'll give you an S+ and a 5,000-dollar year-end bonus." I studied as if my life depended on it, and in the end, I got the acceptance letter. My father slapped a contract down in front of me instead. "Congratulations on onboarding into the next phase. Starting today, your allowance will be structured as base salary plus performance plus attendance bonus. "Base pay is 250 dollars a month, enough to keep you from starving. "To prepare you for a high-pressure work environment, I’ll conduct random inspections. Fail, and your pay gets docked." When I ran a 104°F fever, he cut my attendance bonus, saying my physical resilience didn't meet standards. When I forgot to submit a weekly report because I was buried in schoolwork, he froze all my money. To stay alive, I went behind his back and sold blood at the hospital. At the end of the semester, I held my transcript and scholarship certificate, thinking I had finally earned the highest rating. But my father looked at me without a trace of warmth. "Your S+ bonus has been reallocated. The company decided to invest it in your brother, Harry. He has more potential." I looked at the 100-dollar "consolation prize" he handed me and laughed. So in his company, I didn't even qualify as an "outstanding employee."

After our company's IPO approval is granted, my boyfriend, Derek Calloway, finally agrees to publicize our relationship at the celebratory banquet. Derek and I have been in a relationship for seven years. For so long, he refuses to make our relationship official. He always cites the fact that office romance is forbidden in the company, and that he, as the CEO, should follow through as a prime example. On the night of the banquet, I wait for the news to be broken with bated breath and unadulterated delight. But when Derek stands on the stage, he chooses to utter the name of the new recruit who has just joined the company for two months—Jocelyn Grant. "It's all thanks to Jocelyn's contributions to the project that our company gets to go public. She's the MVP of our company." I just stand beneath the stage, completely stunned. For a moment, I don't know how to react. I'm the main person in charge of that project, and I'm the one who's contributed the most to that project. Not only have I stayed up countless nights working hard on it, but I also got hospitalized a few times because of it. Soon, I receive Derek's text message. "Jocelyn has just joined this line of work. She needs a project to help spruce her resume up. Just let her receive the credits this once. "We'll discuss more on publicizing our relationship in the future." I can only grip my phone so tightly that my fingertips go white. Finally, I key in one word. "Okay." Jocelyn can have the project. She can also have my position as the director. Heck, she's free to have Derek, my now ex-boyfriend. I'd like to see how these assholes can pass the subsequent trials without me.
