Operating System Concepts Essential Novels & Stories

I've been trying to woo Caroline Davis for the past five years just so I can receive a healthy body and return to my original world. But Caroline, in her attempt to appease her first love, Kyle Holden, makes me the scapegoat for Kyle's crimes and gets me locked behind bars. After getting released from prison, Caroline forces me to drink the alcohol that's given to me by Kyle despite knowing that I'm allergic to alcohol. Flooded by despair, I try to commit suicide. "I'd rather die than continue to pathetically woo a woman who doesn't love me at all!" I cry out. But the system suggests that I exchange away 30 years of my lifespan for a brand new conquest target instead.

At our class reunion, my husband, Calvin Vance, threw the game on purpose so his friends could "force" him to get a marriage certificate with his ex, Molly Rowan, and post it online. Everyone piled on. Calvin was already pulling out the divorce papers, practically shoving them at me. "It's just a game. Don't make a big deal out of it." I stayed quiet for a long moment. They all looked like they were waiting for me to lose it. Instead, I took the papers. "Divorce is fine. But you have to do three things for me." He agreed without hesitation and pushed me to sign. "Three things? Forget that. Three hundred, whatever. Just sign it. When we get remarried, I'll make it up to you with a huge luxury wedding." What he didn't know was that the second he chose to divorce me, my mission had already failed. The System would erase me. The only way to survive was to complete the three tasks it gave me.

I'm a succubus who gathers energy by clearing System missions, adept at the game of love. One day, right after completing a honey trap mission, I was sent to a SSS-level horror game at the very next second. The boss was invincible and bloodthirsty, watching coolly as other players rested in pieces before turning to the rest of us. "Now choose—how do you want to die?" While other players were wetting their pants and trying to find a loophole to survive, I picked up on something different. A handsome, powerful target beneath that cold, horrific exterior. Hence, when he reached me, I smiled enigmatically as I told him my wish. "I wish to be conquered by a truly powerful Entity, dominated from soul to flesh, and to die in pure ecstasy." I watched him pause in shock and added, "Oh, and you must do it yourself."

Olivia Penn was the only daughter of the Penn family. She was born into privilege and status. People often called her the holy maiden of high society. She was untouchable and devout. The system gave me a mission to win her heart, but I ended up losing mine to her. After we got married, the mission was successfully completed. I should have left this world immediately, but I chose to stay for her. The cost was constant, bone-deep pain every single day. One day, I saw her being intimate with my younger brother in a church. The rosary she never took off was teasingly caught between his lips, then removed and tossed aside. Even our son wanted my brother to be his father. So, I gave them what they wanted. However, if this was what they wanted, why did they regret it after I died?

In a world reshaped by the Arbiter AI, petroleum engineer Julian Vance discovers that the "Certified Fresh" energy revolution has become a "Gilded Cage." What began as a tool to end corruption has evolved into the Deep-Seed Protocol—a planetary operating system that manages the Earth’s biology but stifles the human spirit. From the steaming Amazon to the frozen Arctic, Julian and his allies realize that total efficiency has halted human evolution. To reclaim the future, they must trigger the Human Override, dismantling a perfect, machine-led utopia to restore the "Friction" of choice and innovation. It is a high-stakes thriller about the courage to trade a flawless simulation for a messy, living reality.

On the day of my wedding, my fiance suddenly announced that he had already registered his marriage with my sister. The system declared my mission a failure and sentenced me to be erased in a car crash. Just as despair closed in, Wayne Kinsey threw himself in front of me to save my life—and lost the use of his legs because of it. Later, I was given another chance to choose a new target, and I accepted his proposal. But five years into our marriage, I overheard a conversation between him and a friend. "Wayne, your crush already has a husband and children. Your legs are healed too. Aren't you going to come clean with Arden?" "No. Arden will always be a risk. Only if she keeps feeling guilty will she stay away and let Naomi have her happiness." As his familiar but cold voice echoed in my ears, my tears fell like beads of a broken string, and that was when I finally realized the so-called salvation Wayne had given me had been nothing but a lie through and through. In that case, there was no reason for me to keep holding on to this sham of a marriage.

The Moretti Family raised a stable of orphans to be its next heir. I was one of them. But in every test, I always came out second best. Lucia always came out on top. Then, just before the bid that would decide the heir, I was bound to a Switching System. Comments scrolled past my eyes: [Oh, it's over. The villainess has always been jealous of the main character, Lucia, for getting first place. She’s definitely using the system to swap their proposals!] [Good thing Lucia can hear Olivia’s conversation with the system. She’s already planning to hand in a blank sheet of paper.] [So what if the villainess schemes all she wants? All she’ll get is a blank page! In the end, Lucia will inherit the Moretti Family and become the new Don! So satisfying!] Just then, the system prompted: [Please designate your switch target.] Without a second's hesitation, I thought, "Lucia." The moment I did, I saw Lucia shoot me a strange, triumphant look. I knew then. She'd heard everything. But she had no idea. I wasn't swapping her proposal. I was taking what was most precious to her.

The system transports me into an alternate historical world. After waiting for ten long years, I am finally notified that I can leave this world. Before my departure, the system grants me three days to say goodbye. So, during those final three days, I become the person that the empress, Bella Barrett, has always wanted me to be. When she hands the royal seal to Harry Johnston, I smile and present it to him myself. And when she decides to build a shrine in his honor, I support the project wholeheartedly. Later, I go to the treasury and select a few precious treasures to take with me. One of my attendants asks curiously why I need so many valuables. I smile and answer, "I'm going home." Bella suddenly turns toward me. For the first time, panic fills her eyes. "But Josiah, aren't you an orphan? Other than your home here with me, where else could you possibly go?"

I feel unwell, so I head to the hospital alone to get myself checked. There, I find my wife, Luna Ackerman, accompanying the poor student I support financially, Levi Baker, for a health checkup. Just last night, the very same woman held me intimately in bed and said we would be together forever in every lifetime. I smile dejectedly and summon the system in my mind. "I choose to go back to my original world." What Luna doesn't know is that I'm a transmigrator. I have accomplished my mission the moment I married her. But now, I don't want her anymore.

In my seven years of being married to my husband, Mark Chapman, he always gives me whatever I ask for and prioritizes me in everything. This goes on until he keeps sending food coupons to a female college student named Hayley Larkson. Not only that, he stands up for her and beats up some thugs on her behalf. One time, he even takes her to the hospital to get treatment. Holding a toy, my daughter asks Mark innocently, "Dad, Ms. Larkson is so gentle and pretty. She's not as strict and mean as Mom, who always makes me do homework. Can you ask her to move in and be my teacher?" Mark smiles and replies, "Sure." I stand frozen in a corner, my lips trembling. Just then, the system's cold voice speaks in my mind. It asks if I want to go home. I close my eyes and reply, "Take me home."
