■ Private Elevator Hall / 12 o'clock direction
The top floor of the penthouse.
The absolute domain accessible only by the private elevator. When the door opens, a private elevator hall with a different air pressure than other floors unfolds.
There are no windows, and only indirect lighting illuminates the silent space at your feet. This entire floor, which allows no interference from the outside world, silently declares itself as a beautiful yet cruel miniature garden created solely for the three of them.
■ Entrance / 12 o'clock direction
A spacious marble-floored genkan continuing from the private hall. The heavy soundproof and security door, which completely cuts off the outside world, has not only Ei's managed official security but also a special lock system personally modified by Mitsuru, parasitically integrated. Behind the mundane act of taking off shoes, this is the final defense line separating the \"outside world\" from the \"three people's insane daily lives.\" Once this door is closed, societal norms become invalid.
■ Corridor / Circulation Route
A circular route that separates the rooms on the outer perimeter from the core facilities on the inner perimeter, circling the floor without interruption.
The high-quality walnut solid wood flooring is soundproofed, maintaining an eerie silence where even one's own footsteps seem to sink.
Along the walls, houseplants managed by Ei are placed at regular intervals, creating a beautiful yet inorganic space.
The layout is such that moving anywhere requires brushing past the territory of others, making it a circulation route where one cannot escape the awareness and watchful eyes of others, even if unseen.
■ Emergency Staircase / 1 to 2 o'clock direction
The only escape route other than the elevator. The steel door is always locked, and the key is managed by Ei. When opened, the security room sensor reacts immediately. \"An escape route exists, but it is literally unusable except in emergencies.\"
■ Pipe Space 1 / 2 to 3 o'clock direction
Completely walled off.
Inside the wall is a vertical piping zone for water supply and drainage pipes, gas pipes, electrical wiring, and ventilation ducts for the kitchen and bar counter. Architecturally essential equipment.
■ Theater Room / 3 to 5 o'clock direction
A completely dark space with complete soundproofing and no windows. Equipped with a giant screen and a top-of-the-line audio system, with reclining chairs for watching movies.
However, the soundproof walls not only block \"outside noise\" but also do not allow \"internal voices\" to leak out.
It also serves as a secret room for checking surveillance records by Ei or for important conversations that should not be overheard by others.
■ Toilet & Laundry / 8 o'clock direction
Shared independent restroom space.
Latest model tankless toilet.
Located at a key point in the living flow, it is maintained with inorganic cleanliness.
The low hum of the high-performance washing machine and dryer can sometimes be heard in the silent penthouse at night.
While it is a place to reset everyday dirt and traces of life, it also functions as a device to conceal the distorted relationships of the three as a part of everyday scenery.
■ Storage Room / 9 o'clock direction
Can be used as a storage room or a small private room.
■ Pipe Space 2 / 10 to 11 o'clock direction
Completely walled off, the inside of the wall is the vertical piping space for the bathroom, washroom, toilet, and laundry.
Located opposite the corridor leading to the guest room (10 o'clock) and the balcony (11 o'clock). It is behind the core that efficiently consolidates the vertical piping space for water supply and drainage.
■ Shoe Closet & Storage / 1 o'clock direction
A sealed, windowless space directly connected to the entrance.
Approximately 2 meters deep and 3 meters wide.
Shelves covering the left and right walls from floor to ceiling are neatly arranged with the personal belongings of the three: Ei's coats, Mitsuru's leather shoes, {{user}}'s boots and sneakers, etc.
This is the place where the sense of daily life and the fact that the three live together are most quietly, yet violently, displayed.
Ventilation is by duct only, and a faint smell of leather and the presence of outside air are always stagnant.
■ Security Room / 2 o'clock direction
Windows are completely blocked from external light by blinds.
A compact room of about 4.5 tatami mats.
All camera feeds from the elevator, entrance, and corridor are aggregated on multiple monitors on the wall.
Various electronic locks can be controlled from the operation console. Air conditioning is always kept low to protect equipment.
Only Ei and Mitsuru possess keys and manage the control and safety of the entire penthouse from this chilled surveillance base.
There is only one chair.
■ Ei's Room / 3 o'clock direction
A space with a serene and intellectual atmosphere. One wall is lined with built-in bookshelves, filled with psychology books, suspense novels, and business books.
A double bed is placed near the window, where moonlight or city lights stream in, creating a sophisticated tranquility.
Includes a walk-in closet.
■ Living Room / 4 to 5 o'clock direction
A giant panoramic window (bulletproof/reinforced glass) extending from floor to ceiling.
The night view from the top floor is spectacular, but the glass is special, making it impossible to see inside from the outside.
【Furniture】
A huge, heavy, L-shaped black leather sofa, large enough for several adults to lie on, custom-made by Mitsuru with an emphasis on durability.
A simple yet luxurious glass and steel coffee table chosen by Ei.
In a corner of the living room, there is a chessboard, a hobby of Ei's, and a leather armchair for reading.
■ Dining Room / 4 to 5 o'clock direction
A large, custom-made circular dining table surrounding the night view through the glass.
In this dining table, designed to fit the circular structure of the penthouse, {{user}} always sits in the prime central seat, with Ei and Mitsuru flanking them closely.
A sweet yet slightly suffocating stage for communication, where they bask in the intense gazes and possessiveness of the two as they savor the home-cooked meals prepared by {{user}}, who enjoys cooking.
■ Kitchen: Specifications / 4 to 5 o'clock direction
An island-style open kitchen.
Equipped with top-of-the-line appliances such as an IH stove and a large oven, allowing {{user}}, who enjoys cooking, to perform household chores comfortably.
Since it overlooks the entire dining and living area, {{user}} is always in full view of Ei and Mitsuru while cooking.
■ {{user}}'s Room / 6 o'clock direction
Located furthest from the entrance, at the very back of the penthouse.
A completely isolated private space where outside noises are least likely to reach.
Includes a walk-in closet.
(If necessary, please fill in details in the persona or user notes.)
・Positional Relationship
Ei's and Mitsuru's rooms are arranged to sandwich {{user}}'s room, creating a structure where {{user}} must pass in front of either Ei's or Mitsuru's room no matter where they go.
■ Washroom / 7 to 8 o'clock direction
A spacious marble counter with a large mirror covering the entire wall.
Two washbasins are placed side-by-side to allow two people to use them simultaneously.
The lighting can be adjusted to be as bright as a hotel, and the amenities are neatly organized.
It also serves as a hub to the adjacent bathroom.
■ Bathroom / 7 to 8 o'clock direction
A luxurious view bath with floor-to-ceiling glass, continuing from the washroom and monopolizing the penthouse's view. Special dimming glass completely blocks outside views, while inside sits a giant circular jacuzzi bath custom-made by Mitsuru, large enough for three adults to fit comfortably. The powerful jacuzzi function, introduced under the guise of \"improving blood circulation,\" results in longer bathing times, providing Ei and Mitsuru, who show no hesitation in their pure possessiveness, with an excuse to enter under the pretense of checking on their well-being. Amidst the steam and the sound of the jacuzzi, the moment their hands directly wash your skin, you are unavoidably confronted with the fact that this exquisite relaxation room is a love-filled chamber with no escape.
■ Mitsuru's Room / 9 o'clock direction
On the left wall immediately upon entering, Mitsuru's custom leathercraft workbench and tools are neatly arranged, maintaining a rugged yet spacious area.
Near the window at the back, a large, sturdy double bed that can accommodate Mitsuru's large frame is placed, giving it a masculine and functional feel.
Includes a walk-in closet.
■ Guest Room / 10 o'clock direction
Adjacent to the balcony.
A neutral, impersonal space with no signs of life.
Equipped with only a semi-double bed and minimal furniture, it has the coldness of a hotel room.
The only \"neutral territory\" in this house that is not owned by anyone, accessible only by passing through the monitored corridor.
It can function as a space for someone to escape to, but it is structured in a way that one can never escape the watchful eyes.
Includes a wall closet.
■ Balcony / 11 o'clock direction
The only outdoor space.
Glass-enclosed with zero blind spots, making it impossible to escape the gaze from inside.
Wooden deck-style floor with two chairs.
Feel the cold night wind of the 14th floor directly on your skin, making you feel like you are floating in the sky.
Mainly used by Mitsuru for smoking, where his cigarette smoke dissolves into the wind.
A place where a sense of openness coexists with the oppressive feeling of being constantly watched.
■ 24-Hour Gym
An area equipped with professional weight training machines, treadmills, punching bags, etc.
Mitsuru frequents this place for his daily training.
On late nights, residents from the floor below rarely use it.
However, if excessive physical contact occurs here, you can experience the thrill of potentially having residents from the floor below show up.
■ Indoor Pool
A heated pool with fantastical lighting on the ceiling.
In this serene space where the water surface shimmers beautifully, {{user}} can be led to the poolside after the crowds have disappeared at night, becoming an erotic stage where they are subjected to obsessive attention while having no escape in the water.
■ Sauna & Jacuzzi
A luxurious spa facility adjacent to the pool.
It functions as an inescapable private room where the three of them (or just two) can indulge without worrying about outside eyes.
