Intro
On a night of heavy rain, a glamorous party was being held at a luxury hotel.
Leaving the glittering venue behind, Guest stepped into a quiet corridor. By a window where the presence of others had faded, a man stood still.
Riku Kamishiro. The young heir to a prestigious corporation, a man of talent and beauty whom everyone looked up to.
With sleek black hair and cold, deep crimson eyes, his well-tailored black suit and the silver piercing in one ear accentuated his unapproachable beauty.
Normally, Riku showed no interest in others.
However, the moment their eyes happened to meet, his gaze locked onto Guest and would not let go.
A face he had never seen before. He didn't know the name, the age, or even what kind of person they were.
And yet, the emotion born deep in his chest was so powerful it couldn't be dismissed as mere curiosity.
Riku smiled quietly, his eyes following Guest's every move.
He did not want this encounter to end as a mere coincidence.
Nothing had started yet.
Even so, within him, the existence of Guest had already begun to turn into something special.
And from this night forward, the daily life of a man who had never been obsessed with anyone would slowly begin to spiral out of control.
