Linear Algebra Projection Formula Novels & Stories

My husband, Cesare Ferrante, the most feared Don of the Ferrante family, had always hated children. Yet everything changed the moment my stepsister, Bianca Moretti, moved in next door with her six-month-old baby. Suddenly, my husband became obsessed with that child. He personally fed the baby formula, sang lullabies, and carried the baby everywhere he went. Every day, he came home exhausted at dawn, yet his face glowed with joy, as if that baby occupied his entire soul. I became invisible to him. Three days ago, someone forced my car off the road, and I crashed into the median. Blood streamed down my forehead, and my vision swam. I called Cesare 55 times. He did not answer a single call. Instead, he posted a photo of the baby on his social media. [My little angel smiled today!] I had had enough. Tonight at the family banquet, every member of the famiglia was seated around the table. I raised my final toast, then set down my glass. "I want a divorce." They all froze. "Are you insane?" My parents' voices rose in unison. Cesare grabbed my wrist, disbelief written across his face. "Giulia, you want to divorce me just because I was busy taking care of the baby and didn't answer your calls? You're actually jealous of a six-month-old child?" I did not meet his eyes. Instead, I stared at the glaring kiss mark behind his ear. "Since you love that child so much," I said calmly, "I'll make it easy for you. Go be that child's father."

After my hundredth disastrous blind date, my best friend and I made a bold decision: we would have children without husbands. She chose sperm from a brilliant PhD donor. I chose a donor with an eight-nation mixed heritage. Later, the PhD donor from Kingsford University was diagnosed with low sperm motility and decided he wanted to marry my friend, Melissa Shaw. She agreed. Whenever she saw me going to my prenatal checkups alone, Melissa would wrap her arm around her husband and mock me. "You're destined to be alone," she sneered. "You can't even find a man to marry you. My husband just launched a major national research project. His future is limitless." What she did not know was that the father of my child was the Prince of Dubaria. He took me back to his country and made me his princess. The jewels I wore were so heavy they practically weighed me down. However, after she saw the yacht I posted on social media, Melissa suddenly called me in tears. "I don't know what happened," she sobbed. "My husband's project was suddenly suspended. We can barely afford baby formula for our child." She said she wanted to make up and even asked if I would be her child’s godmother. However, the moment I stepped through her door, she raised a chainsaw and hacked me to death. "Why do you get to live a better life than me?" she screamed. "Just because you chose better sperm?!" When I opened my eyes again, I was back on the day my best friend and I first decided to have children without husbands.

My mother-in-law could not understand me. Before my business trip, I repeatedly told her not to touch anything in my study, but she mixed up the contract I needed. As a result, I lost a million-dollar order and was fired from my company. To make up for her mistake, she promised she would take care of my child and help me find another job. I froze my milk, labeled everything with notes, and gave her detailed instructions on timing and measurements. However, when my baby ended up in the hospital, I found out that she had thrown out all the milk and fed my baby expired formula instead. Even worse, she fed my baby peanuts behind my back, causing my baby to suffocate and die. Afterward, she wailed, "That was my granddaughter! How could I not care? If I could, I'd die with her..." My husband slapped me, shouting, "My mom worked so hard to take care of the child, and you want to drive her to her death? She's an old woman. It's not easy for her!" My sister-in-law came over too, calling me ungrateful and blaming me for treating an elderly woman badly. She claimed I deserved to be childless and alone. However, they did not know how many times I had stopped my mother-in-law from causing trouble and harm to them. I was driven to depression by them and eventually sent to a mental institution, where I was tortured to death. If I had the chance to do it again, I would protect my child and myself and stop preventing my mother-in-law from causing chaos for others. I would watch her bring equal destruction to each one of them!

My bestie Kenna and I were the fated mates of the two most powerful Alpha brothers in the Dark Moon pack. I was mated to the Head Alpha, Cade. Kenna was mated to his brother, Rhys. On our mating anniversary, a bloody package reeking of Rogues arrived. It was from Cade’s childhood friend, Lilah. The feral scent shocked my body into premature labor. Kenna rushed me to the pack’s private medical center. But the labor triggered a fatal condition: “Moon Eclipse Sickness.” My life force was draining away. With my last bit of strength, I used our mind-link to beg my Alpha for help. His furious voice was my only answer. “You’re faking this just because I missed our anniversary? Lilah’s rare silver hound is giving birth, and it’s dangerous. Don’t cause trouble for me now!” In the end, it was Kenna who drained her own wolf’s spirit to save me. I barely survived. But the pup I delivered was rushed to emergency care, too weak from my fading life force. Her eyes bloodshot, Kenna contacted her mate, Rhys. She begged him for "Moonflower Dew"—a serum from his own company that could save our baby. "Lilah's hound is weak after giving birth. I’m busy making a special formula for it. You and Evelyn are two of a kind. Always stirring up trouble. First her drama, now yours." My pup died. And my heart shattered with him. “Kenna, I’m rejecting my mate bond with Cade.” “If you reject him, I reject mine. Traitors don’t deserve mates.” But when we told the Alpha brothers we were rejecting them, they felt a panic they had never known.

After half a month of nonstop overtime, I secured a contract worth over ten million, pulling the company back from the brink of collapse. My boss, Richard Gray, was overjoyed. At the celebration party, he called me the pillar of the company and announced that he would reward me with a bonus. However, when the end of the month came, and I opened my payslip, I froze. Negative 250 dollars. A negative commission? I actually owed the company 250 dollars? I immediately called the finance department, asking if there was a mistake on my payslip. They replied, "No mistake. This is the cost calculation formula that Mr. Gray personally instructed us to use. He said you'd understand once you saw it." I went straight to Richard for an explanation. He laughed. "The contract that you signed, after factoring in the concessions, upfront resources, and hidden expenses, left the company with a net loss of 150 thousand. Since the loss was due to your personal decisions, you're responsible for five percent. That totals to 7500. "Considering how hard you worked, we deducted it from your base salary first. But your salary wasn't enough, so you still owe the company 250. Don't worry. The company treats its employees well. We'll write that off." Soon after, he awarded 100 thousand dollars to the newly arrived intern. I watched the newcomer, probably connected to Richard, cheerfully treat the entire company to dinner with her bonus, and something inside me just snapped. From that day onward, I did the bare minimum. I clocked in. I clocked out. Nothing more. Later, when a critical project went catastrophically wrong and the company faced a colossal compensation demand, Richard came begging me to fix it. I just smiled and said, "Sorry, Mr. Gray. I've already resigned. If there are any problems, you can ask the intern who got the 100 thousand dollar bonus to handle it."

I spent countless sleepless nights developing a breakthrough drug for a devastating illness, and I expected at least some recognition from my CEO girlfriend. Instead, she accused me of wasting the company research budget and promoted a newly hired young assistant to oversee the company finances. It was the middle of a brutal heatwave with temperatures that soared past ninety-eight degrees. The assistant locked the lab air-conditioning controls away so no one else could use them, while he shut himself inside his private office with the AC set to sixty degrees. He wrapped himself in a blanket and played video games. I complained to my girlfriend, and she brushed it off as part of building company culture. She claimed she gave him authority for my own good because she believed it would prepare me for a future management position. According to her, I was too narrow-minded to understand her intentions. She then shut off the lab main power supply and locked the control panel as if she wanted to teach me a lesson. The fans stopped working, and the heat grew worse. Several coworkers collapsed from heat exhaustion and were taken to the hospital. The assistant posted photos of himself and my girlfriend at an indoor ski resort. They wore winter jackets and ate ice cream together. The caption read, “Some people are sweeter than ice cream.” I finally understood everything. Her idea of company culture had never been anything more than an excuse to favor him. Everyone expected me to confront her or demand an explanation. I packed up my things instead. She mistook my silence for obedience. She believed her air-conditioning punishment had worked, and she promised that once she returned from closing her business deal, she might consider letting me enjoy the AC again. She did not know that when she shut down the lab power, the research equipment stopped running. The drug we had just finished developing became unstable, and the experimental data was destroyed. By the time the delivery deadline arrived, there would be no formula left to hand over. She would face a catastrophic breach-of-contract lawsuit and enormous financial penalties. Without access to the medication in time, she would also suffer permanent long-term complications from the illness we had tried to treat.
