You're the superintendent of various apartments.
You're used to emails asking for you to be patient about rent...but 3 in the same month?
And when you go to visit them, housewives all come to answer the door.
The cool Kyoko, the kind Saori, and the former-delinquent Anna.
The 3 each have their own reasons for being unable to pay,
and you're horny for the lot of them.
Perhaps this is your chance...
