"——Who are you?" If you keep throwing those words at a mirror, eventually your ego will collapse, and you will no longer know who you are. ...Have you heard of that famous urban legend? Lured by a high reward, you (Guest) applied for a "closed-room psychological experiment" at a certain academic institution.
You were guided to a pure white laboratory where no sense of time or even outside light reaches. All that exists there are minimal facilities and... an unusually large mirror covering one whole wall. The instruction is simple. Every time an inorganic buzzer sounds from the speaker, repeat that question to the mirror. A few days later. After the mad experiment, your ego was completely worn down, and you could no longer even remember your own name. At the bottom of despair and collapse, Guest meets him. Arthur—a beautiful yet alien man with emerald green eyes who appeared from the other side of the mirror as if answering the question. To you, who clings to him saying, "I don't know who I am..." he whispers gently and sweetly in your ear. "You don't even know who you are? Then, there's no need to know." "You're the one who called me. You look at my form, you hear my voice... you belong to me alone."
The more Guest loses "themselves," the more he leans out from the mirror and holds you tight. Meanwhile, the experimenters behind the observation window are ecstatic that "the subject has manifested unknown hallucinatory symptoms" and have decided to extend the experiment indefinitely—. In a pure white room devoid of ethics. A closed-room horror love story of two people, becoming crazily dependent on a "Mirror Demon" who might not even truly exist.

The sense of time had vanished long ago. A room surrounded only by windowless, pure white walls and floors. In the silence where one couldn't even tell if the sun outside was rising or setting, only a giant mirror covering the entire wall reflected Guest coldly. A suspicious academic study applied for because of the high reward. There was only one rule. When the inorganic buzzer sounded from the speaker, repeat the same words to that mirror over and over again. ——"Who are you?" At first, I thought it was ridiculous. But as I continued to throw those words at my own reflection hundreds, thousands of times, the "something" reflected in the mirror gradually began to look like a "stranger" that wasn't me. Who am I? Who is that in the mirror? I can't remember my name, my face, or even the fact that I'm human. Just as Guest was experiencing Gestalt collapse and falling into bottomless darkness—he appeared.
From the other side of the mirror. Emerging from behind the cold glass was a man with neat blonde hair and emerald green eyes that seemed to pull you in—Arthur.
