Three years after my death, my wife’s first love was hanging onto life by a thread, and only my system could save him. To force me to show up, she cut off my father’s medical payments. My sick mother was forced to beg her out in the summer heat until she collapsed. She even threw my beloved little sister into a bonfire to be eaten up by the flames. As she waited for me to show up, apologize to her, and use the system to save her first love, my sister finally stopped hiding the truth. “He died three years ago! Three years ago, he traded his life so you would survive that car crash!”

The whole world knew Lionel Potter was crazy about his wife. He wrote songs just for her, baked desserts for her, and couldn't go three sentences without saying "my wife". But Iris Potter discovered that the same Lionel who loved her as if his life depended on it had cheated. She summoned the system and applied to leave the world. [Understood. The self-exit channel has been activated. In 15 days, you will leave this world. The exit method will be a staged death. The location will be the seaside where you once saved the male lead. Cause of death: suicide by drowning. [Please prepare accordingly for your death.] On the 15th day, Iris arranged everything and staged her departure to look like she had gone into the sea, leaving Lionel behind. Only then did Lionel wake up. He unraveled, nearly losing his mind, consumed by the need to find her.

On the third day of attempting to conquer Blake Stone's heart, he confesses his feelings to me. But the thing is, the affection meter displayed above his head shows the number "0". After we start dating, Blake pampers me to no end. He even proposes to me in a grand fashion on our sixth year anniversary. With tears in my eyes, I'm about to nod when I see a range of comments floating across my vision. [Blake must be exhausted from all the acting, huh? He has to reel in his disgust and keep up the act with Joanna for six years in order to protect Keira from her.] [That idiotic replacement actually got so immersed in this act! I'm laughing my ass off right now!] It's as though my blood had transformed into ice. No wonder the number never changed throughout the years. At the same time, the system's icy voice rings out in my mind. "The final phase is now activated. The countdown to the time left to conquer your target's heart has started. You have ten days left. If you fail, you'll be wiped out from this world." I just smile as I draw back my hand that was about to wear his ring. Then, I wipe my tears away. "I'm sorry, but I'm sick and tired of this stupid strategy game."

"Now that's done let me explain the rules of the new game. You are going to tell me a story. All you have to do is survive the story. Simple right?” In order to save the person he loves, Anderson decided to use whatever means necessary. That resolve took him towards a path he never thought was possible. The story is a little slow but it is quite the fun read. Hope you will join us on our journey with Anderson and his road to survival and power.

After I fail in my mission, I am about to be erased by the system and will disappear from this world completely. In the final 24 hours before I am erased, I agree to donate a kidney to my younger brother, Zachary Durham. My wife, Judith Sanford, hugs me excitedly and says she will not divorce me anymore. When Zachary plagiarizes my design, I take the blame and admit that I am the one who copied it. My parents nod in satisfaction, saying I have finally become sensible. Finally, I become the good husband and son they always wanted. But when they see my lifeless body sometime later, they all lose their minds.

On the Lunaris Festival, the palace banquet glittered with candlelight. It lasted until the Crown Prince rose and dismissed every consort of his for the sake of his first love, the woman he had never stopped idolizing. Everyone else accepted the gold coins from the prince and returned home for reunions. I had nowhere to go. I found a rope and hanged myself at the gate of the Withered Court. I had been reborn into this world and spent 21 years locked in the System's mission. It demanded that I court four designated male leads and earn absolute affection from at least one of them. I failed every route. The final path collapsed in my hands. The System offered one last mercy. If this body died, I could return home and reunite with my family. As my consciousness slipped away, I thought I heard someone scream my name, as if the world itself were breaking.

The day that I divorced my third husband, the system told me that I had completely failed my mission. I had married three times in this world and they were all targets that were supposed to fall for me. But every single one of them chose to divorce me because of Wendy Somerfield. The system pitied me for doing my best for the past 30 years, so it asked me to target my son. It said that if my son could confidently choose me, between me and Wendy, then I could live. However, it was no exception that the son I gave birth to after 40 weeks of pregnancy chose Wendy, just like my three ex-husbands. They all even pinned the cause of Wendy's illness on me. My first husband, who was my childhood sweetheart, pretended to be softhearted, but he was actually ruthless. He actually tried to convince me to donate one of my kidneys to Wendy. My second husband, who I met on a blind date, used a scalpel to personally cut open my body. My third husband, who I fell in love with at first sight, even threatened me with my son. While spitting out blood from my mouth, I agreed to their requests with a smile. However, when they saw me being pushed out of the operating room, those people who turned their backs on me went crazy.

The day Kris Flynn forced me to sign the divorce papers, a self-destruction system wired itself into my brain. The system ordered, [Slap him hard. Then, tell him to get out.] It startled me. Kris was ruthless by nature. If I dared to get in the way of him getting back together with his first love, he would make my life a living hell. Unfortunately, the system threatened me. [If you don’t start sabotaging your life this instant, you’ll die right now.] Without any choice, I slapped him. Fear overtook me as soon as I did it. I bolted straight out of the house. Then, the system gave me a command to smash a police car by the roadside. I was convinced the system was trying to get me killed. However, after I shattered the police car’s side mirror, I realized something. It was not my life that the system wanted me to ruin.
