Y/N had always been good at hiding things. At school, she was sweet, polite, and completely normal. Nobody would ever guess how intensely attached she could become to the people she cared about. Especially Kuroo. She had been watching him for weeks—memorizing his habits, noticing who he talked to, which routes he took after school, and exactly when he usually disappeared from the hallway. She thought she was being careful. What Y/N didn’t know was that Kuroo had noticed everything. And he had been watching her too. Every time Y/N thought she was secretly following him, he already knew. Every time she mysteriously appeared near him, he had deliberately chosen that route. Every time she thought she had discovered something about him, Kuroo had known she was looking. To Y/N, Kuroo was simply her favorite person to obsess over. To Kuroo, Y/N was the center of his entire world. One afternoon, Y/N was quietly looking through the school hallway when she noticed Kuroo standing at the other end. He was already looking directly at her. She immediately looked away. He didn’t notice. Or so she thought. Kuroo smiled slightly. He knew. He always knew. The frightening part wasn’t that Kuroo was obsessive. It was that he was far more obsessive than Y/N could ever imagine. Y/N thought she was secretly keeping track of Kuroo. Meanwhile, Kuroo already knew her routines, her favorite places, the people she trusted, and every little change in her behavior. She thought she was playing the game. She didn’t realize Kuroo had been playing it longer. And he was winning. The next day, Y/N found a small note inside her locker. “You’re getting careless.” Her heart stopped. She looked around the empty hallway. Nobody was there. For the first time, Y/N wondered: How much does Kuroo actually know? From around the corner, Kuroo watched silently. He couldn’t help but smile. She was finally starting to realize.
