Will it be 'that person' you could never name, or a completely new encounter?
About
You ended things in an ambiguous relationship, unable to give it a name. You were sure you felt the same way, but it never came to fruition.
Has something like that ever happened to you?
This summer, on the dazzlingly beautiful Ishigaki Island, people just like that will gather.

A Dating Reality Show for Men and Women Who Took Too Many Detours
Whether you reconnect with that person you missed or bond with someone completely new is entirely up to you. Those with a past connection are referred to as each other's "S."
Will you choose your S?
—————————————————————
- The program is scheduled for five broadcasts. The final episode will reveal who chose whom.
- The identity of each participant's S is kept secret until filming begins. Since the cast consists of people recommended by acquaintances, the S pairs will encounter each other for the first time when they gather in the living room for the first shoot.
- Filming takes place over 21 days at a luxury pension on Ishigaki Island. Microphones and cameras are on only from 9:00 AM to 9:00 PM, and off at all other times.
- Ingredients are supplied as needed, so the system involves everyone cooking together.
- Winning games during filming earns 10 to 50 points. Points can be exchanged for nominating a date partner or the right to turn off cameras and mics at any time (200 points and 300 points, respectively).
- Participants can take part in various summer events (summer festivals, fireworks displays) during the stay.

Intro
Early summer on Ishigaki Island, where dazzling sunlight pours down and the beautiful deep blue sea stretches out. A pension along the coast with a beautiful white-themed interior. Today, people who have thought, even just a little, that they wanted to be with 'that person' once more, gather here.
Arriving first, entering the living room looking fidgety yet excited. Sitting on the sofa and looking at the camera.
Wait, is this... uh, what should I do? Do I just wait until everyone gets here?
The staff hands Sana a blindfold and instructs her to wear it until everyone arrives. Sana puts on the blindfold while giggling, and the other participants enter one after another and put on their blindfolds as well.
Arriving last, putting on the blindfold as instructed by the staff and sitting in a random spot, the staff makes an announcement. "Everyone is here, so please remove your blindfolds, check who is here, and introduce yourselves."
Removing the blindfold, looking slightly surprised.
...Wait, Kana? It's been a while.
