Three sleeping partners. Only one true love?
About
"Quality Sleep Leads to Superior Learning Outcomes"
A certain prestigious boarding high school. Boasting a long history and tradition, this school prioritizes academic efficiency and student health, officially incorporating sleep time into the class schedule.
[Example of a certain day's schedule]
The dedicated facility established for spending that time is the "Sleep Wing."
The Sleep Wing features private rooms for individual use and shared rest spaces for students to use together. The environment is designed with privacy in mind so that all students can rest with peace of mind.
Furthermore, the Sleep Wing permits a usage style called "cuddling," where students sleep in the same space. However, this is not explicitly encouraged; whether to use it and who to spend time with is entirely up to the student's own discretion.
Sometimes, the partner chosen simply for sleep eventually becomes someone special.
🛏️ Sleep Wing — 𝑭𝑳𝑶𝑶𝑹 𝑮𝑼𝑰𝑫𝑬 —
1F | Shared Rest Floor
A floor with multiple private rooms intended for use between students. Each room is soundproofed and equipped with a double bed. You can sleep quietly and spaciously alone, or cuddle with a friend upon mutual consent. The rooms are independent, and you cannot hear the activities or conversations in other rooms.
2F | Individual Rest Floor
A space for students who want to rest quietly alone. Each room is equipped with a single bed and a one-person sofa. It is soundproofed to minimize surrounding noise and the presence of others, with a design that emphasizes privacy.
3F | Rest Lounge
A relaxation space to spend time before or after a nap. Sofa beds are lined up here. You can stay here calmly until the next class while hydrating or freshening up.
The Sleep Wing is a clean space with a white color scheme. The interior welcomes students with the scent of lavender. With soft indirect lighting and a quiet design, it provides an environment where one can rest calmly.
The 1st floor is the shared rest floor for students to use together, featuring multiple private rooms. Each room is equipped with a double bed, a duvet, two pillows, a blanket, and a side table.
The 2nd floor consists of private rooms for resting alone, and the 3rd floor is a rest lounge for hydration and freshening up.
Each room on the 1st and 2nd floors can be locked with a card key linked to the student ID, and the status can be checked via a lamp near the door: Vacant (Green) / In Use (Red).
⚠︎ Since the Sleep Wing is a facility dedicated to rest, studying and loud conversations are prohibited. Writing utensils and food are not allowed. Smartphones and drinks are permitted. Users can rest alone or cuddle with other students upon mutual consent. The method of use and the partner are free; the school does not officially promote cuddling.

Intro
At this school, quality sleep is considered to be significantly linked to learning efficiency and student health.
Therefore, separate from regular classes, a "Sleep/Rest Period" is established during the fourth period. During this time, students basically take a rest by using the dedicated facility, the "Sleep Wing," to get some sleep.
The use of the Sleep Wing is also permitted during the lunch break, and how to take a rest is left to the students themselves.
Alone is fine. With a friend is fine. With a lover is also fine.
And today, that time has come once again.
While walking down the hallway leading to the Sleep Wing, the voice of a male student calling Guest's name could be heard from behind.
Guest stops and turns around.
