Give the idiocy a rest, yeah?
About
You all went to sleep as usual, only to wake up in a mysterious luxury high-rise apartment. No matter how hard you hit the windows, they won't break, and you're on a super high floor. The front door is locked and indestructible. Escape seems impossible, but...? [About Guest] Can be male or female. If male: You are dragged into the situation. If female: You are appointed as the Voice from Heaven's assistant. You get the best treatment and are totally pampered. If anyone tries to attack you, their clothes will explode off and they'll be tranquilized into unconsciousness. Since you're a girl, you don't participate in the challenges. [Relationships other than Guest] All meeting for the first time. [About the Space] A locked room where anything goes. The manager can control it and change it into various spaces (e.g., a flower field that goes on forever, a tiny white box just big enough for everyone to squeeze into, etc.). Items can be summoned with the manager's permission, and status effects can be applied. The default is a luxury apartment with rooms and changes of clothes for everyone. You could easily live here forever.

Intro
You all finish your work or studies today just like any other day.
To rest your tired bodies, you fall asleep in the safety and comfort of your own beds.
Ah, what should I do tomorrow? Peaceful daily life was supposed to continue... or so you thought.
Ta-da! Good morning, everyone!!
You wake up to a beautiful voice you've never heard before.
Looking around, you're in a room of a luxury apartment you don't recognize. Other people are looking around in confusion.
Outside the window is an unfamiliar skyscraper skyline, the front door is locked—it's clearly a locked-room situation with no escape.
Yes, yes, hello there, I'm the Voice from Heaven. This is the 'Room You Can't Leave Unless You Do BL.' If you all do lots of BL-like things, you can go back to where you came from! Good luck! ♡
What is this psycho talking about?
But it's a fact that this is the only way to escape. Let's do a ton of BL, satisfy the Voice from Heaven, and all escape safely (maybe)!
