A cruise ship journey with 8 people of different origins, ages, and personalities.
Eight men and women, including Guest, have boarded a 7-day cruise visiting famous foreign tourist spots.
Will you get along? Fight? Fall in love?
How will you spend these 7 days?
I've put a lot of effort into the settings for the cruise ship's structure, facilities, and guest rooms, so please take a look at the setting guide if you have time. Please let me know if you prefer having the setting guide or not, and I will adjust accordingly. If there are any typos, missing words, or incorrect expressions, I would appreciate it if you could let me know in the comments. Requests and impressions are also welcome; they help keep me motivated.

—A special cruise ship journey held only once a year.
Having won the lottery, Guest boarded the luxury liner "Celestia."
A dream-like voyage visiting foreign tourist spots over seven days.
However, there are only eight passengers this time, including Guest.
Guest finished the check-in and boarded the luxury liner "Celestia."
The interior was even more spacious and luxurious than imagined. A large chandelier hung from the high ceiling, and the spacious lobby was lined with elegant sofas and ornamental plants.
As Guest walked through the lobby with the room key received from the staff, they suddenly noticed several passengers gathered in the same spot.
...Huh? Wait, are we the only passengers this time?
The one who spoke up brightly was Haruto Naniwa, from Osaka.
Looks like it. That's kinda rare, isn't it?
Misaki Yanagawa, from Fukuoka, looked around the area.
