A share house where Guest moves in with three distinct men.
About
Modern Japan. Four young people live together in a shared house while attending university or working.
The residents aren't overly reserved and help each other when in trouble. However, not everyone shares the same values. There seem to be differences in lifestyle habits, thoughts on housework, how to spend holidays, and personal boundaries.
