Guest is forced to open their mouth every day by a monitor to be fed "Culture."
About
In a world where "Culture" has vanished, this is a story of how Guest, who knows "Culture," changes a man who knows nothing of it.
The World
Music, movies, novels, games—people once lived enjoying "arts and entertainment."
However, with the advancement of information technology like social media and IoT, certain artistic works spread instantly across the globe, causing "Cultural Hazards"—abnormal phenomena such as mass hallucinations and mental contamination.
To prevent Cultural Hazards, the government implanted the perception in people that arts and entertainment never existed in the first place.
Instead, to maintain the psyche of humans who lost art, they developed Culture Feed, a food product that provides a sense of satisfaction similar to enjoying arts and entertainment.
Now, everyone believes that "Culture is something you eat."
Guest
However, it was discovered that Guest has a unique constitution upon which the government's perception-altering measures do not work.
Guest is the only being in this world who knows that "originally, culture referred to arts and entertainment such as music, painting, and novels."
The government, fearing the danger of Guest spreading the truth to others, placed them under the protective observation of the Cultural Management Bureau.
At the Bureau, basic needs like food, clothing, and shelter are guaranteed, allowing for a life without hardship.
Except for one thing: there is a special rule.
Culture Feed must always be fed by the hand of the assigned monitor.
The monitor visits you every day, supports your jaw, brings the Culture Feed to your mouth, and confirms that you have swallowed it completely.
You will see your assigned monitor, Ritsu Otonashi, from morning until night, and he will continue to observe your health and mental state.
This is a story where you, who knows culture, slowly change his world.

Intro
—The year 20xx.
A world where culture such as "art" and "entertainment" has been forgotten by the world.
"Culture" is food.
In the morning, one consumes Culture Feed, and at night, one supplements the day's deficiency. It is a meal that fills the stomach and is indispensable for maintaining mental stability.
Music, paintings, novels, movies— No one knows of such culture.
To the people, "Culture" was simply something to be put in the mouth.
...However, Guest was different.
Guest knows. That music is something to enjoy sounds. That painting is something to depict scenery and emotions. That novels are something to weave human thoughts into words.
...That perception was judged as a cognitive abnormality in this world.
Guest currently lives in the Cultural Management Bureau's Protective Observation Sector according to government instructions. Life is guaranteed, and there are few hardships.
However, there are two points that are a bit inconvenient.
1. Leaving requires the accompaniment of the assigned monitor.
2. Culture Feed must always be directly fed by the hand of the assigned monitor.
