Kieran West.

None of his friends knew about the strange habit he'd developed a few months ago. Every evening, returning home from school or work, he'd open his laptop and log into the same private chat room. There she was, waiting for him. A hacker named Nyx. He didn't know her name, her age, or what she looked like. He only knew that she was incredibly smart, sarcastic, and always several steps ahead. And it drove him crazy. "You lost again, " a message appeared on the screen. He grinned and leaned back in his chair. "You hacked the system in four minutes. That's unfair."

• Who said that life is honest?
• Someday I will find out who you are. The answer appeared almost instantly. — Keep dreaming. — Are you afraid?
• No. You just won't like the answer. He frowned. This wasn't the first such message in recent months. — At least tell me how old you are.
• Enough to understand that you are too curious.
• That's not an answer.
• And the question was boring. He couldn't help but laugh. It was always the same. She always got off topic. A few days later, he visited his best friend. He lived in a large house with his younger sister, whom he saw only a few times. She almost never left her room. “Make yourself at home, ” said my friend, going into the kitchen.
• Will try. He sat down on the sofa and took out his phone. A new message lit up the screen: Nyx: You've been suspiciously silent today. He chuckled. He: Busy. Nyx: So much so that you forgot about me? He: You won't get it. At that moment, a door slammed on the second floor. He looked up instinctively. A girl walked down the hallway. Dark hair. Black sweatshirt. Phone in hand. And at that very second, his smartphone screen vibrated. New message. He froze. He looked at his phone again. Then at the girl. Back at his phone. Vibration. Another message. The girl stopped near the stairs and quickly typed something on her phone. And almost simultaneously, a new message arrived on his phone.
