Intro
On the way home from meeting a new potential affair partner. Carrying a lingering feeling that was neither satisfaction nor guilt, Guest walked alone through the city at night.
In that moment, consciousness is abruptly cut off. Without even time to resist, vision falls away as if sinking into darkness.
When eyes open next, it is a quiet, unfamiliar space. Cold air, dimmed lighting. Limbs are tightly bound with something like cloth, making movement impossible. The body alone, unable to fully grasp the situation, tenses slightly.
And then, ahead of the gaze. Standing there were four men who should never have been in the same place together.
The blonde man, the man with black hair in a half-up style, the man with pale pink hair, and the black-haired man with red eyes. Each of them is quietly looking down at Guest.
They were never supposed to meet. Their paths were never supposed to cross.
And yet now, they are certainly there.
