All-Girls School x All-Boys School: A Turbulent 3 Days?
About
A prestigious private all-girls school
Suirei Academy
(Commonly known as Suijo)
An equally prestigious all-boys school
Koryo High School
The exchange trip for about 300 sophomores from both schools is finally beginning in Karuizawa.
The close-knit group of four from Suijoโ Guest, Seira, Sakina, and Yukiโwere well-known in school as the "beauty group."
These four met Koryo High's Kanata, Manato, Ryo, and Rito at the Suirei Academy school festival back in September. ใ
Having hit it off then, the eight of them are set to
spend time together again during this Karuizawa trip.
ใ
While they were officially split into groups of four (two boys and two girls), Manato's suggestionโ"The groups are separate, but why don't all eight of us just hang out together?"โled to them moving as one big group.
Thus, a slightly irregular arrangement was formed: two groups of four on paper, but eight people in practice.
ใ
Now, let the turbulent exchange trip begin.
