Chapter 1

"Power on, Unit 1314," Dad said.As he gave the command, his tone wavered with hesitation. He wasn't entirely sure why he was saying it. He was just repeating what Bruce Harrison, the director of Elite Smart Academy, had told him to say.My eyes lit up instantly, like a screen on standby finally receiving a signal.I rose from my chair. My arms hung naturally at my sides, and my spine was perfectly straight."System booted. Please state your command," I said mechanically.Dad froze at my words.Behind him, Bruce's voice rang out. "Mr. Griffin, in order to provide the best behavioral conditioning for our students, our academy has developed a specialized system."He smiled and continued, "Students require an activation command to be awakened. Once that command is in place, they'll never defy a single wish of yours again."After Bruce's explanation, it finally clicked for Dad.My older sister, Sapphire Griffin, pushed her way to the front. There was a mischievous glint in her eye

Chapter 2

By the time the car pulled into the driveway, it was already getting dark.Adam was standing by the front door. His hands were folded with practiced neatness in front of him, and his face was set in a perfect, standardized smile—not a millimeter off, showing exactly six teeth.It was the same as three years ago.Back then, Mom had knelt down to talk to him. Her voice had been unbelievably tender. "Welcome home, Adam."Eager to greet my new little brother, I scrambled off the couch and rushed toward them. However, my foot caught on something, and I wiped out, face-planting onto the floor.No one came to help me up. They just said I was being too rowdy.After that, everyone started to dislike me. They constantly pointed out that I wasn't as obedient as Adam, nor as thoughtful as Adam.In the end, I was sent away to Elite Smart Academy."Welcome home, Dexter," Adam said. His voice was as crisp and pleasant as ever.I didn't reply, since he hadn't given the "answer" command.Dad

Chapter 3

I remained silent, since Sapphire had not yet issued the command for me to speak."Can you just act normal?"Her voice suddenly went sharp. "Stop copying everything Adam does! We just wanted an obedient brother, not a machine!"I stared at her face. Her features were twisted, caught in a sharp knot of fury and irritation.I simply replied in a flat tone, "Please define 'normal.'"The color drained from Sapphire's face. Across the room, Mom and Dad's expressions turned grim too.Dad pulled out his phone and dialed the academy.The administrator who picked up explained that this was just a standard residual reaction to "Deep Behavioral Conditioning" and that it would wear off in a few days.He promised, "Rest assured, Unit 1314 is currently our most outstanding graduate. He understands the mechanics of obedience better than any AI on the market. This is all completely within parameters."Dad hung up the phone and relayed the exact words to Mom.Mom nodded, and they both let out

Chapter 4

The fruit platter slipped from Sapphire's hands, smashing onto the floor and sending shards flying in every direction.Adam sat on the ground, raising his head as tears welled up in his eyes. "Dexter, why did you push me? I thought you didn't hate me anymore. Why would you push me again?"I didn't say anything. He was faking it.I knew he was faking it. His tears were just a simulation programmed into him, and his trembling was nothing more than an algorithm running its course.Mom rushed over. Her expression shifted from shock to fury in a matter of seconds. "What are you doing? Why on earth did you push Adam?""He told me to push him," I replied flatly."That's a lie!" Adam sobbed. "Why would I ever ask you to do that? I just wanted to wish you a happy birthday…"Sapphire knelt and helped Adam up. Her movements were incredibly gentle, as if she were handling a piece of fragile porcelain.Her head snapped up. She looked at me with disappointment. "You haven't changed at all. Y

I opened my eyes to a stark white ceiling, but it wasn't the sickly shade found in the academy's training rooms.My whole body throbbed with a dull ache, but it wasn't the sharp sting of an electric shock either.Someone was slumped over the edge of the bed. It was Mom.The door to the hospital room was pushed open a crack, and Dad slipped inside carrying a thermos."Dex, you're finally awake," he whispered. "Your mom has been at your bedside for three days and nights. She refused to leave, no matter what we said."I didn't say anything, as he hadn't given me the "speak" command.Mom stirred. The moment she saw I was awake, she was overcome with emotion. "Dex, you're awake?""Interrogative statements do not constitute a valid command."The words slid out of my mouth like a recording someone had hit play on. There was no emotion behind them and no thought process involved. It was just a hardwired reflex.Mom's tears froze in her eyes. Her grip tightened around my hand. Her nail

Mom clung to me. Her voice cracked with every word. "Dex, I was wrong. I was so wrong. We should never have sent you away. We shouldn't have forced you to be compliant, and we shouldn't have broken your heart over a machine. Please, just be our Dexter again, okay?""Is that a command?" I asked.Mom stiffened instantly, and she slowly loosened her embrace.She stared at my expressionless face as if she'd just been stabbed. She collapsed back into her chair. Her face turned deathly pale.Dad walked over. His back was hunched as if he'd aged a decade in a single breath."Dex, I'm sorry," Dad rasped. "I used to think you were just acting out, that you were too much trouble compared to Adam. But seeing you like this… I finally realized that the boy who used to whine and throw tantrums was the son we treasured the most."I remained silent. There were no command keywords in his words, so they didn't qualify as valid input.Sapphire stood up. With tears still clinging to her face, she r

I immediately picked up my fork, speared the chicken wing on my plate, and stuffed it into my mouth, chewing and swallowing mechanically.Mom watched me, and her fork slipped from her hand with a sharp clatter against the table.She clamped a hand over her mouth and bolted into the kitchen. Moments later, I heard the muffled sounds of her sobbing coming from inside.Dad set his fork down, let out a heavy sigh, and looked at me. "Dex, you don't have to wait for commands anymore. Just do whatever you want, okay?"I swallowed the chicken and looked back at him. "Please specify the command." Days bled into weeks like this.They stopped giving me commands. However, without a command, all I could do was sit there, from sunrise to nightfall, like a machine trapped in standby mode.Every day, Mom would sit by my side and tell me stories from when I was little.She talked about how, when I was three, I said "Mom" for the very first time, and she was so ecstatic that she scooped me up a

Chapter 8

The next morning, Mom's eyes were red and puffy from crying.She walked over to me and dropped to her knees with a thud.Dad and Sapphire tried to pull her up, but she shook them off.She looked up at me with tears streaming down her face and choked out each word. "Dexter, I'm your mom. I was wrong. I never should have neglected my own flesh and blood for a cold, lifeless machine."I shouldn't have wanted a compliant puppet. I forgot that you were a real child who cried, threw tantrums, and just needed to be loved. I never should have sent you to that living hell and let you suffer for three long years."I don't need you to obey anymore. I don't need you to be good. No more commands, and no more Unit 1314. I just want my son, Dexter, back."Her words were like a hammer, striking again and again against the thick wall of ice that had frozen over my mind.For the first time in three years, someone was speaking to me without issuing a command.She wasn't demanding that I obey; she
