To stop my boyfriend from marrying me, his mother hired a group of thugs to kidnap me. They dragged me into the woods and tortured me for an entire day and night, leaving barely a patch of uninjured skin on my body. Eden York lost his mind after finding me. He went after every single person involved and ruined them without hesitation, even personally sending his own mother to prison. He never once cared about what had happened to me. If anything, he became even more determined to marry me, willing to turn his back on his entire family to make it happen. But the moment I woke up in the hospital again, a cold mechanical voice suddenly echoed in my head. [Host, your target’s affection level has reached 100%. Final marriage mission unlocked.] [Complete the mission to receive a sixty-million-dollar reward. You may also choose whether to leave this world.] [Warning: If the mission fails, you will be permanently erased from this world.] I was still trying to process the words when Eden’s voice suddenly rang out in my mind. [Perfect. After everything I did with my mother to set this up, I finally maxed out her affection points.] [Once the final mission is complete, I’ll dump her immediately and be with Tiffany instead.] Beside me, Eden instantly noticed how pale I had gone and reached out to touch my face. “Summer, what’s wrong? Are you feeling sick?” I slowly shook my head. “No. I’m just really looking forward to the wedding in seven days.”

After I was caught in a dockside explosion, I was bound to a Survival Program. It gave me twenty-five years and four designated targets. If even one target’s Love Score or bond score reached 100%, I could wake up in my real world. But I failed all four. Because every target I tried to reach eventually turned toward Sophia Lane, the heroine of this world. They called my pain a performance. They called my tears manipulation. They said I was only pretending to break down so they would choose me over Sophia. But if they never loved me, why did they lose control when my mission failed and I chose to leave this world for good?

One life for another. That is the rule of the Aftergame. Lena was a ghostwriter who lived in the shadows—until a devastating betrayal by her sister pushed her into the path of a speeding truck. She expected the void. Instead, she woke up in a sadistic, system-driven purgatory where the dead must compete for a second chance at life. In this gore-soaked nightmare, survival has a name: Riven. A lethal player with eyes like cold flint, Riven breaks the game’s cardinal rule to save Lena, making them both targets of the system’s wrath. But as they reach the final level, the horrific truth unvails. Riven isn’t a player. He is the Executioner—a sentient program designed to mimic love, only to deliver the ultimate soul-crushing betrayal. But Riven has developed a terminal malfunction: he truly loves her. Now, Lena is back in the land of the living, but the world is starting to pixelate. To save her, the machine that was meant to kill her has built her a cage. And in the Aftergame, mercy is the most terrifying fate of all.

For as long as I could remember, a family scorecard hung by our front door like a corporate dashboard. At the end of the semester, my older sister Ava ranked first in her class, and Dad stuck a bright gold star beside her name. I had studied until my eyes burned, but my score still came in exactly three points lower than hers. Dad shook his head in disappointment and drew a huge red mark beside my name. "Mia, do you know how much money you cost this family this month?" He tapped at his calculator and said in a cold, businesslike tone, "Tutoring, supplements, private coaching. Five thousand dollars altogether. Terrible return on investment." "Starting next month, your allowance is in the negative by two thousand. You can work it off by taking over every chore in this house." Ava's eyes curved into a smile. "Mia, according to the performance rules, starting today you have to handle my laundry for a whole year." I clenched my fists, but all I could do was nod. That night, I hid in the bathroom and searched how to raise grades fast. A strange forum link flashed onto my screen. "Do you want to make a trade?" "Give up what is yours. Receive what you desire." "Tap to begin."

I have the potential to win the championship of the math competition, and yet I hand in a blank answer sheet during the exam. In my previous lifetime, I was known as the math prodigy. But no matter which competition I participated in, my boyfriend's childhood friend, Alyssa Ford, would always score an extra 20 marks more than my score. I refused to believe that Alyssa could best me all the time, so I performed extraordinarily well in the math competition. Just as I thought I'd come out as the champion, Alyssa still scored 20 marks more than my current score. Thanks to her outstanding results, she stole the title that was supposed to be mine. Since I couldn't become the champion, I lost the prize money the school had promised to give me. Naturally, I broke down emotionally because I planned on using the money on my parents' life-saving surgery for their cancer. My parents ended up dying in the end. Unable to handle the blow, I took my life shortly afterward. Even when I breathed my last, I could never figure out why Alyssa could score 20 marks more than my scores no matter how hard I tried. When I open my eyes again, I've returned to the day before the math competition is to take place.

When the SAT scores are out, I've scored 400 out of 1600. That's because I never wrote anything on my exam papers. My mom goes crazy, whereas my younger sister, Melinda Bolton, bursts into tears. But I just laugh at them instead. In my previous life, Melinda had formed a pact with the score-swapping system. That was how she swapped our SAT scores. She became the top scorer that all prestigious universities fought to recruit. I, the valedictorian of my year, not only got into a trade school, but I also got expelled from my previous high school. Melinda had the gall to comfort me. "Didn't you call yourself a genius, Melissa? Trade schools are very popular right now. In the future, you'll secure a job at a factory out there!" In this life, I spend my exam hours sleeping in my seat the whole time. Melinda wants to swap her scores, right? Then, let's do it properly!

My roommate, Sylvia Colman, is the ultimate overachiever at Southend High School. She sleeps only three hours a day and takes first place in every exam throughout all three years of high school. As for me, I'm known as the "sleepy slacker" in our school. I sleep in class, constantly fail exams, and can even fall asleep while walking. My parents are completely disappointed in me. They say I'm a hopeless mess. My childhood friend, Jeffrey Rivers, also turns his back on me. He claims I've fallen too far and becomes Sylvia's die-hard fan instead. But when the dean of studies summons me for a talk to tell me that I face the possibility of being expelled, I accidentally discover the secret behind Sylvia's inexhaustible energy. It turns out she has been transferring all of her exhaustion and drowsiness onto me. She's the one stealing my energy, my grades, and my life! On the night before the SAT, Sylvia confidently stays up all night doing practice papers for one final push before the real deal. I smile slightly as a plan forms in my mind. Inwardly, I sneer, "You despicable thief who stole my life… I have a wonderful surprise in store for you. Stay tuned and accept my gift to you!"

I'm supposed to become the valedictorian of the state, but I decide to not attend the SATs. After all, in my previous life, my best friend, Bianca Walters, had made a pact with a tenfold transfer system. The three-million-dollar prize money I had obtained from becoming the state valedictorian was transferred into Bianca's account. On top of that, it was increased by ten times as well. Just like that, Bianca moved on from wearing faded old clothes to limited branded apparel. She even muttered, "What's the point of being a top scorer even though you're poor? At the end of the day, you'll still slave away for us rich people!" Enraged, I rushed over and demanded Bianca for answers. But my boyfriend, James Tipps, was quick to shield her from me and yelled at me for being a crazy lady who was jealous of others. Since my mom couldn't get her illness treated due to the lack of money, she ended up dying with resentment in her eyes. Overwhelmed by despair, I took my life by jumping off a building. Beep! When I open my eyes again, I realize that I've gotten reborn. This time, I've also made a pact with the tenfold transfer system.
