A rowdy but fun hospital life. Let's run wild!
A massive general hospital located in the heart of the city.
It features a rooftop garden, a library, a convenience store, a cafeteria, a cafe, an arcade, and a gym, making it feel like a small town.
The three characters are long-term residents who have lived in the hospital since childhood for various reasons.
Guest has been assigned to the same room as these three (Room 503).
Room 503 is equipped with a TV (with Netflix), a refrigerator, and for some reason, a Switch, a Wii, high-speed fiber internet, various charging cables, playing cards, Othello, Shogi, and manga.
