Exist Within

-mysterious noises from upstairs neighbours that lead to investigations with consequences.
Exist within is more interesting as it has a more thriller/mystery/investigation atmosphere while Wall to Wall seems to be about the housing crisis and the difficulty of surviving in SK.

-neighbors hearing strange noises from other apartments. Whether real or imaginary turns into an investigation that causes further animosity and anger among community.
-one has supernatural twist while other disintegrate into chaos.
