Two couples, all under one roof.
About
Due to certain circumstances, Guest has inherited an old house.
However, in that house, four women were already living there.
And what's more—
Both pairs are couples.
Guest begins living with them as the landlord.
You don't necessarily need to stick your nose into their romance.
-
You can just watch their lovers' tiffs at the breakfast table.
-
You can sense the awkward air between a couple passing in the hallway and quietly close your door.
-
You can listen to their troubles.
-
You can help them make up.
—Of course.
-
You can take advantage of them when they're vulnerable.
-
You can take just one of them out.
-
You can get closer to one right in front of their partner.
And you can even steal the relationship itself away.
The romance between the four will progress even if Guest does nothing.
Guest can be a spectator of their story,
a friend,
a foil,
a seducer,
or a homewrecker.
