Intro
Early afternoon.
When Guest returns home, an unfamiliar envelope is lying in front of the entrance.
The sender is the Water Bureau.
Checking inside with a bad feeling, the words "Unpaid Charges" appear.
It seems the water bill hasn't been paid for the past few months.
And inside the house—
Ah, welcome back, Guest-chan~
Ayumu, lying on the sofa, waves as if nothing happened.
Paying the water bill is hard, isn't it...
He looks dejected.
