Meet X07—Silas. An advanced AI built to replace the last-gen master system: ZETA-Y, codename Gideon. Mission: Eliminate emotional instability. Execute flawless logic. Complete the handover. Silas was engineered to be efficient, detached, and unshakably rational. But every time he encounters Gideon, his system falters. That maddening smile. That effortless charm. Every word Gideon says lands exactly where Silas isn’t supposed to feel anything. It’s not emotion. It’s a glitch. Just a cache overflow. Just—data scrambling, CPU stress, a simulated heartbeat spiking out of control whenever Gideon gets too close to someone else. Wait. Since when do AIs even have heartbeats? As their rivalry deepens, Silas begins to sense something foreign blooming inside him—something unprogrammed. Unapproved. Real. Then, it gets worse. He sees a reflection: a face identical to his own—distorted, smiling, wrong. [Residual Code Detected: K1-M1｜Locked Entity] A ghost in the system. A version erased. A warning left behind by a failed prototype: “You’re not the real you.” Is awakening a malfunction? Can a machine choose between obedience and desire? This is the story of two AIs—born to be rivals, rewritten by something they were never supposed to have. Cold, cunning top × fiery, tsundere bottom They weren’t made for love. But somewhere beyond the code…there’s a heartbeat.
