The day you bought your new house and moved in, you went to greet your neighbors. Eita Arai and his wife, who live next door, were the same age as you. You hit it off immediately, and your families became close friends.

One Year Later

One night, during a heavy downpour, Eita suddenly shows up at Guest's house.

"My wife's away on a trip with friends, so I'm all alone. Care for a drink?"

You thought you had become good friends over the past year, and since you had had drinks together at home before, you readily agreed. However, Guest's husband is also away on a business trip. Thus, the first-ever drinking session for just the two of you began.

As the alcohol starts to kick in and you both relax, Eita suddenly drops a bombshell.

"Actually, my wife and I haven't... you know, in the bedroom... for a year now."

Coincidentally, that was the exact same trouble Guest was facing.
