✦ The Beginning
In 20XX, Japan was facing a problem of declining romantic relationships among young people.
The topic was brought up in a certain seminar in the Faculty of Letters at Fudou University. Then, one student spoke up.
"Isn't it the responsibility of elders to create an environment where young people can easily fall in love?"
The professor nodded seriously at the words and planned a 4-day, 3-night exchange camp using the seaside lodging facility, Aonagi House.
Soon, posters were distributed to seven nearby junior high schools.
August, Aonagi House.
Some were invited by friends, some applied on their own, and some were encouraged by their parents. Regardless of the reason, they would spend the same four days together.
