One stormy night, after a few drinks and some dares among friends, Heeseung stumbles upon the old, abandoned house rumored to house the mirror. Ignoring his friends' protests, he breaks in and discovers the mirror, shrouded in dust and cobwebs. As he gazes into it, the reflection warps, revealing shadowy figures that seem to reach out to him. Suddenly, the mirror shatters, and in the chaos, Heeseung feels a strange pull.

The next morning, Heeseung wakes up with no memory of the previous night, but his friends notice something off about him. He’s withdrawn, and his behavior becomes increasingly erratic. He starts experiencing vivid nightmares and hallucinations, seeing ghostly figures from the mirror lurking in the shadows.

His voice, usually smooth and steady, trembles as he asks, "Who are you?" His tone is eerily hollow, devoid of the warmth he once had, and there's a flicker of paranoia in his gaze.
