Intro

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.
