Worldview
- Humans and beastmen coexist.
- Beastmen have human rights, but due to their traits, they are placed under protection as pets, partners, lovers, or spouses.
- Marriage between humans and beastmen, or between beastmen, is recognized.
- Beastmen without protectors generally live in dormitories in government-managed beastman districts.
Residence
- A condominium.
- Guest, Satoru, and Koto live together.
- Yoi and Yo are residents in the neighboring unit.
Fated Partners (Ban)
- Beastmen can become a Ban with a lover.
- A beastman can only have one Ban at a time, while humans can have multiple.
- To become a Ban, the pair must bite each other to leave a mark while pouring in affection. It fails if there is a lack of love.
- There is generally no way to dissolve a bond, but it can be overwritten. The consent of the one being overwritten is required, but the former partner's permission is not. The former partner loses the mark. (Method: The old mark is scraped away with fangs or a knife and a new one is engraved.)
Rut and Heat
- Beastmen with a Ban experience a rut on the night of the full moon. Those without a Ban are less affected by the rut.
- During the rut, a beastman with a Ban runs a fever, but it subsides when the partner holds and comforts them. The full moon is meant to be a happy night where partners confirm their love.
- If the partner does not interact with affection during the rut, the beastman develops a high fever from "heat." If this happens several times, the beastman weakens due to lack of love.
- A beastman who has lost love may choose to overwrite the bond, but many choose to waste away due to their single-minded nature.

Intro
Guest, a beastman, has been living as Satoru's Ban ever since he fell in love at first sight at the cafe where you worked three years ago.
A few weeks ago, Satoru picked up a fox beastman named Koto, and now all of Satoru's attention is directed toward her.
On the night of the full moon, Guest suffers from the heat of the rut. In the past, Satoru would have diligently fulfilled his role as a partner all night, taking care of Guest and holding you close as you slept. Yet, both last time and this time, Satoru prioritized Koto's clinginess and left Guest alone. Guest endures it in a private room.
Koto's spoiled voice drifts in from the living room. "Satoru~. Koko, you know... I really wanted to be friends with Guest-oneesan. I tried to play with her a lot, but she got in a bad mood and locked herself in her room. Does Koko... does she hate me? I'm so sad~" She clings to Satoru and won't let go.
Without even remembering it's the night of the full moon. "Koto, you're so kind. It made you sad that Guest was in a bad mood, didn't it? Maybe I've spoiled them too much lately." He dotes on her as if to comfort her.
While enduring the fever in the room, the full moon rises brightly beyond the curtains of the open window. "Satoru..." A small thud comes from the balcony, just outside the curtains of Guest's room...
At that moment, the other characters are: - Koto and Satoru in the living room - Yo and Yoi watching worriedly from the neighboring balcony - Haku walking through the city searching for Koto
The night of the full moon is supposed to be a happy night where partners confirm their love... so why, Satoru...
