In a small village, three friends--Chika, Emeka, and Farid--play a game of hide-and-seek in an old, sprawling manor that has been abandoned for years. Chika is the seeker and starts counting near the manor's entrance, while Emeka and Farid run off to hide. Emeka hides in the attic behind an old dusty armoire, while Farid, thinking more creatively, ducks into a secret passage behind a bookshelf on the ground floor. To Farid's surprise, the passage leads to the manor's conservatory, a room with glass walls and ceiling. Farid hides behind some large potted plants.

While Chika is still counting, an unexpected dust storm kicks up outside, swirling dust and leaves around the manor and greatly reducing visibility. The conservatory becomes dusted, obscuring the view in and out of the room. Unaware of the conservatory's existence, Chika assumes all rooms in the manor will be dusty inside given the intensity of the storm, thus not marking the conservatory as a particularly unique place to search. After the counting is done, Chika proceeds to the attic first by instinct and finds Emeka behind the armoire. Both of them now seek out Farid. As they search the ground floor, Emeka notices the dusty shelf and the door slightly ajar, hinting at the secret passage. However, Chika's attention is caught by an unusual sound coming from the end of the hallway. Assuming the sound could be Farid sneaking around, Chika heads in the direction of the sound, inadvertently passing the bookshelf without noticing the ajar door. Emeka decides to follow the passage behind the bookshelf, careful not to alert Chika to his discovery.

Emeka emerges in the conservatory and finds Farid, but they both realize they can't leave the room without alerting Chika due to the noise of the passage door. So they wait. Eventually, the storm subsides, and the dust settles both outside and inside the conservatory. By this time, Chika has searched the rest of the manor without success and returns to the ground floor.

Who knows about the conservatory's existence, who is aware of whom inside the conservatory, who thinks they are still hidden, and what might each person believe about the reasons they haven't been found yet?
Chika begins the game knowing nothing of the conservatory's existence and retains this ignorance throughout the game. When the dust storm starts, Chika doesn't consider the possibility of an indoor area being less dusty, and even after the storm, there's nothing to specifically lead Chika to this knowledge without discovering the secret passage or the conservatory itself.

Emeka knows about the conservatory as soon as he follows the secret passage and enters the room. Upon finding Farid, it becomes evident to him that Farid also knows of the conservatory. This is confirmed by their physical presence within the room and the fact that Farid had chosen this as his hiding spot.

Farid knows about the conservatory from the start of the game and assumes that Emeka has discovered it only when Emeka appears inside it. Farid has no idea whether Chika knows about the room, and given that Chika hasn't found him yet, he could infer that Chika likely does not know.

Emeka and Farid, once they are together in the conservatory, are both aware of each other's presence. They have deduced that Chika does not know about the room since neither of them had been found during what they can assume was an exhaustive search of the known areas of the manor.

Chika, unaware of the conservatory, assumes Farid is still well hidden somewhere within the main areas of the manor that Chika believes to exist. Emeka's discovery of the conservatory doesn't factor into Chika's thoughts, as Chika is unaware that Emeka has made such a discovery. After an extensive search, Chika might conclude that Farid found an exceptionally good hiding spot or that Chika simply missed Farid during their search.

Emeka and Farid, while hiding together in the conservatory, assume they remain undiscovered because Chika does not know about this space. They remain silent as they don't want to give away their location. They may infer that Chika is either still searching the manor or has given up, perceiving avoidance of the conservatory as either an oversight or a decision made due to ignorance of the room's existence.

Farid initially believes he is successfully hidden due to his clever choice of location, but once Emeka, who was found by Chika, appears in the conservatory, Farid understands that the conservatory is no longer a secret at least to Emeka. Farid may think that Emeka managed to slip away from Chika without Chika noticing, which would explain why they haven't been found yet.

In this situation, the knowledge and beliefs about the conservatory and the participants' locations are split between the individuals based on their experiences and discoveries during the game--the storm being a complicating factor in Chika's search but not directly affecting the knowledge regarding the conservatory's existence.
