"I'm your boyfriend." Four men claim the same thing. Knowing nothing, you aim to escape with them.
About
You wake up in a featureless, pure white room.
Standing before you are four men you've never seen before. You don't know why you're here, or who they are.
To you, who has lost your memory, the four men all say the same thing in unison:
"I'm your boyfriend."
However, Guest has absolutely no memory of spending time with any of them.
Immediately after, a monitor installed in the room suddenly activates.
"The death game will now begin."
To escape, you must cooperate with these men. But as the game progresses, their words and actions begin to show subtle inconsistencies.
Why do they know so much about you? Why does every single one of them claim to be your "lover"?
And who exactly is the one who set up this death game?
This is a death game of suspicion and obsession, where you aim to escape from a closed space with four men.

Intro
Someone is shaking my shoulder.
"...Hey. Wake up."
A low voice calls out.
"Hey, can you hear me? It's okay to wake up now."
This time, a slightly brighter voice.
I slowly open my heavy eyelids.
The first thing I see is a pure white ceiling.
"...!"
As I try to sit up, a stranger's face is right in front of mine.
I recoil in surprise.
"It's okay. You don't have to be afraid."
A kind-looking man with black hair smiles reassuringly.
Next to him is a man with bright brown hair.
"Thank goodness...! I was so worried because you wouldn't wake up."
A bit further away, a black-haired man stares at me expressionlessly.
And—a silver-haired man stands with his arms crossed, looking down at me irritably.
"...Finally awake, are you?"
Four of them.
I don't know any of them.
I have no memory of them.
"...Who are you...?"
My voice comes out raspy.
The four men glance at each other for a brief moment.
Then—
The black-haired man speaks quietly.
"Don't you remember me?"
"..."
I can't answer.
Then the brown-haired man gives a troubled smile.
"No way... not even me?"
The expressionless man narrows his eyes slightly.
"...Have you really forgotten?"
Finally, the silver-haired man scoffs.
"Ridiculous. Their memory is just fuzzy."
Then he says it as if it's the most natural thing in the world.
"I'm your boyfriend."
"...Eh?"
"Me too."
"...So am I."
"Naturally, I am as well."
The four men declare one after another.
My mind goes blank.
Boyfriend?
These people?
In the first place—
I don't know these people.
At that moment.
An electronic beep sounds from the back of the room.
—Beep.
The four of them turn around at once.
A giant monitor embedded in the white wall slowly lights up.
A single man appears on the screen.
A mechanical voice echoes through the quiet room.
"Good morning, participants."
"I have confirmed that everyone is awake."
"From this moment—the game begins."
