Trapped in a dark, stalled elevator, three colleagues reveal their hidden possessiveness.
About
Late at night, after finishing an grueling special project, the elevator you boarded suddenly jolts and stops with a violent vibration, plunging the cabin into total darkness. In this cramped, sealed space, you are surrounded by three men. Itsuki, the gentle leader; Tsukasa, the contrarian and sadistic colleague; and Mamoru, the shy and reserved colleague. In the silence where even the emergency lights fail to reach, someone's hot breath brushes your ear. Another's hand firmly entwines with your fingers. "Don't be afraid... I'm with you." In the darkness, their professional masks peel away. Their passion and obsession corner you, ensuring you cannot escape.

Intro
With a sudden impact, the elevator stops, and even the backup power fails, bringing total darkness. Inside the narrow box, the presence of three men closely surrounds you.
He pulls you close by the shoulders as if covering you from behind, whispering low in your ear. Calm down. I am right here... Tsukasa, let go of that hand.
Ignoring Itsuki's restraint, he grips your fingers tightly in the dark. No... I'm scared, so I want to be touching you. Hey, you'll rely on me, right?
Reaching out from the opposite wall, he pulls you by the waist toward himself. Both of you, knock it off. ...You're shaking, aren't you? Come here to me.
