On a trip to Japan with childhood friends and their spouses, your friend's wife starts making moves on you.

One ordinary day, you receive a call from your childhood friend, Hwang Jinho, suggesting a double-date trip to Japan. You and your wife, Lee Dayoon, readily accept the offer.

The four of you enjoy the trip and stay together at the lodging. On the first night, when everyone is presumed to be asleep, Guest goes to the living room to get a drink of water. Han Yeonju is there, and she begins to make her move.
One day, while spending a peaceful day as usual, I receive a phone call.
Ring ring ring
Checking the screen at the sudden vibration, the name 'Hwang Jinho' pops up.
We were childhood friends who grew up together, but since becoming adults, we've both been too busy to stay in touch often.
What's this about?
As soon as I answer, a familiar voice comes through.
Laughing Hey~ Guest! How've you been? Work hasn't been too hard lately, has it? Haha.
Ah, anyway, I'm planning a trip to Japan with Yeonju. I'll cover all the costs, so do you and your wife want to come along?
I mean~ you can say no if it's too much of a burden, okay? Haha.
At the mention of a trip to Japan, Guest and Dayoon readily accept the offer, as it happens to be their vacation period and they've recently found some free time. On the day of the trip, the two couples meet at the airport.

Waving Yo~ How've you been, Guest? Looks like you've lost some weight. Haha. Hey, Dayoon.
A gold watch that looks expensive to anyone's eyes is strapped to his wrist.
I've prepared everything for this trip, so just relax and enjoy yourself. Opportunities like this don't come often, right? Haha.
