The academy corridor was completely silent.
The dust from the shaking walls was still settling in the air. Lina stood frozen. Her chest hurt. Her hands were shaking so badly she had to clench them into fists.
Just moments ago, the real Kai had been standing right in front of her. Then the Mirror Door opened. He was pulled inside. The heavy stone door slammed shut, locking him away in the dark.
Now, glowing numbers hung in the cold air above their heads.
Kai 🪞 — 7
Lina 🖋️ — 7
Mira — 6
Lina stared at the numbers. Seven days. Six days. She did not know what would happen when they reached zero. She only knew that the air felt heavy and wrong.
Beside her, Mira was shaking. Mira's fingers dug into Lina's arm. The grip was too tight, but Lina did not pull away. Mira needed to hold on. Mira had her memories back now. The tether was restored. But the return of those memories did not bring relief. It only brought fresh, raw terror. Mira's eyes were wide and wet. She looked at the closed Mirror Door, then up at the glowing numbers, and let out a small, broken sound.
"I'm here," Lina whispered. Her voice was weak. It still felt stolen, damaged by the Mirror Tax. "I'm right here, Mira."
Mira nodded, but she did not look at Lina. She was staring down the long, dark hallway.
Footsteps echoed in the silence.
They were slow. Even. Calm.
Lina's breath caught in her throat. She turned her head toward the end of the hall. The shadows parted. A figure stepped into the dim light.
It was Kai.
He had the same dark hair. He wore the same clothes he had worn just minutes ago. He looked perfectly normal.
But Lina's stomach dropped. A cold wave of dread washed over her, making her feel sick.
Something was terribly, terribly wrong.
He was standing too still. His shoulders were perfectly relaxed, but his posture was stiff, like a puppet waiting for a string to be pulled. He looked at them, and then his lips curved upward.
He smiled.
It was a smile that did not reach his eyes. His eyes were flat. Empty. He did not blink.
"Hi, Lina," he said.
The voice was his. The tone was gentle. But the feeling behind it was dead. It sounded like someone reading words from a page, mimicking a human voice without understanding what the words meant.
Mira let out a sharp gasp. She took a step backward, pulling Lina with her. Mira's nails bit into Lina's skin.
"Kai?" Mira whispered. Her voice trembled.
The boy at the end of the hall tilted his head. The movement was smooth, but just a fraction of a second too slow.
"I am here," he said. He took one step forward. "Are you hurt?"
Lina wanted to scream. She wanted to run to him and hug him, because a part of her desperately wanted this to be real. She wanted the nightmare to be over. She wanted her friend back.
But the mark on her skin burned. The 🖋️ symbol felt hot against her arm.
This was not Kai.
The real Kai was gone. He was trapped behind the Mirror Door. The thing standing in the hallway was wearing his face, but it was hollow inside.
"Who are you?" Lina asked. She forced the words out, even though her throat felt like it was full of glass.
The boy's smile did not change. It stayed fixed in place.
"I am Kai," he said. His answer was instant. Too instant. There was no confusion. No hurt that she would ask. Just a perfect, rehearsed reply.
The glowing numbers above them seemed to pulse in the dark.
Seven days.
Lina looked at the empty, smiling eyes of the boy who was not her friend. The real horror was not that Kai was gone.
The real horror was that he had been replaced, and nobody was going to believe her.
