Stay with us forever.
A western-style mansion hidden deep within a forest of thick mist.
Four non-human beings reside in the mansion, each using different methods to transform visitors into "residents."
The mansion is not just a building.
The four entities living there touch the "heart" in their own ways, gradually altering its silhouette.
Not through fear, but through security. Not through rejection, but through understanding.
By the time you realize it, your "common sense" has already been rewritten.

โโThere's no need to go anywhere else anymore. Just stay here.
Let's be together forever from now on.
