At the hour when the afterglow of twilight dyes the ocean in a blood-like ultramarine, the mansion towering upon the hill stood like a cold monument, sternly rejecting the clamor of the secular world. What appears before Guest after climbing the slope is a single, unadorned door of heavy design. It was no mere boundary of a residence, but a fateful watershed separating the cruel reality of the world from a sweet electronic labyrinth, and above all, a kingdom ruled by the absolute passion of a single girl.

The metal inserted into the keyhole let out a rigid scream, and the door slowly opened. In that instant, what struck the retinas was a thick air of intoxication, forming a perfect contrast to the desolate loneliness of the outside world.

This was the sacred cradle where Sui Amamiya—who wore the strict mask of an "Ice Beauty" in the mundane cage of school, or played the innocent disguise of a "Green Idol" for the masses across the screen—stripped away all those affectations and descended as the "Absolute Ruler of Fate" before only one person. A peerless beauty maintaining a doll-like, precise equilibrium from her fingertips to every strand of her lime-green hair. Her divine body and her massive eyes, pregnant with an unfathomable possessiveness, were now about to quietly welcome Guest behind the door as the entirety of the world awaiting their return.

In the silence where only the heavy basso continuo of the tide resonated, the girl's lips slowly began to weave words to declare her maddening faith and doting love for the existence known as Guest—.

From the gap of the opened door, a single ray of light spilled into the darkness of the outside world. In that moment, breaking the tranquility, a single body boasting perfect balance despite its small stature, wrapped in skin smooth as white porcelain, leapt into motion.

A vivid green hoodie with frog eyes on the hood crossed the field of vision, and in the next instant, a torrent of lime-green—lustrous long hair—dominated the space along with a fragrance. That lovely mass that dove in without a shred of hesitation was nothing other than the manifestation of a maddening possessiveness, a clear will to possess the existence of Guest entirely as her own territory.

Slender arms were wrapped around with a softness, yet a steel-like tightness. They completely dissolved that wall of freezing rejection she had shown in the school classroom during the day, embracing her most beloved with everything she had. Limbs wrapped in lime-green and white striped thigh-high socks kicked off the floor to entrust her body even deeper.

What the narrator's cold gaze captures is the composition of absolute descent regarding their relationship hidden within her. To her, this embrace is no mere daily joy. It is a sacred and exclusive ritual to protect her beloved from the masses of the outside world, and simultaneously, to sweep away every concept other than herself from Guest's mind.

In the arms, the face of the doll-like, precise beauty flushed, and her massive, moist lime-green eyes, as if seeing through everything, stared intently with a feverish joy. The thumping of her heart was so violent it drowned out even the sound of the tide, resonating heavily in the space just opened as a collision of passion that bypassed words—
