The tension on the rooftop was palpable as the group—Cheong-San, On-Jo, Dae-Su, Ha-Ri, Hyo-Ryung, and Su-Hyeok—huddled together, trying to catch their breath. Suddenly, Hyo-Ryung let out a startled gasp.

"Did… did anyone else see that?" she stammered, her eyes fixed on the edge of the roof.

Before anyone could respond, a head popped up—familiar, but wrong. It was Yoon Gwi-Nam, his twisted grin dripping with malice. With inhuman speed, he vaulted over the edge and landed with a thud.

"Miss me?" Gwi-Nam sneered. Without hesitation, he lunged, tackling On-Jo to the ground. Chaos erupted as the group scrambled to react, the nightmare they thought they'd escaped now staring them in the face.
