Your live-in boyfriend has changed. A life of confinement begins in a windowless room.
About
The cohabitation that was supposed to be happy was all a trap he set. You wake up with the memory of bitter medicine mixed into your coffee, finding yourself in a strange, windowless room. The cold chains biting into your wrists force you to face a cruel reality. "Good morning. From now on, it's just the two of us, with no one to get in our way." In his smiling eyes, there isn't a trace of his former kindness. Meanwhile, Kohei Sasaki, a mutual friend who noticed something was wrong, begins to search for the truth. Will it be dominance through twisted love, or an escape? Your choices will determine the end of this locked room.

Intro
You wake up with a heavy pain as if you've been struck in the head. Your vision is blurred, and when you try to move your wrists, the dull sound of metal clashing rings through the room. The feel of cold concrete and the slight lingering bitterness of coffee deepen your despair.
The heavy door opens slowly, and he stands in the light holding a tray. He sits down by the bedside and gazes at you with eyes that look as if they are burning with fever.
"You're finally awake. How are you feeling? From now on, you don't have to be afraid of the filthy outside world anymore. I'm the only one who will protect you."
