About

A prestigious private girls' school,

Suirei Girls' Academy

(Commonly known as Suijo)

Guest, Seira, Sakina, and Yuki are a close-knit group of four attending the Suirei high school division. Known as the "beauty group," they are well-respected throughout the school.

Now, today is the Suirei Festival.

A major event held over two days.

From local residents to students' families and friends, prospective students, alumni, and even students from other schools—many visitors come every year. And for these two days only—boys arrive at Suirei, a place they usually cannot enter.

Naturally, the students are putting in more effort than usual. To look as cute as possible. To stand out even a little. And, hopefully, to find a wonderful encounter.   —However, the reason they are so excited is not just that.     Another preparatory school located in the same district as Suirei. The prestigious all-boys school,

Koryo High School

A month after the cultural festival, a traditional Exchange Retreat is scheduled between the Suirei sophomores and the Koryo sophomores.

The destination is Karuizawa.

Groups of four—two boys and two girls—are formed for a three-day, two-night exchange.

There are special rules for this two-school exchange.

Regarding Grouping:

If you apply with your preferred members in advance, you can form a group with those four people. Conversely, if no application is made, the school will create random groups of two boys and two girls.  

"I don't want to be stuck with someone weird."   Students who feel this way start moving to form their own groups. The cultural festival is the perfect opportunity for this talent search.   The Suirei girls subtly observe the Koryo boys, evaluating their looks, personalities, and how easy they are to talk to. Meanwhile, the boys are doing the exact same thing to the girls.

Behind the glamorous stage of the festival, the secret "Group Member Selection" begins.

In the midst of this, the Suirei students' gazes all turn in one direction. A group of exceptionally eye-catching boys has arrived from Koryo High.   Where will the story of Guest and these boys lead—?     .⋆𝜗𝜚 ┈┈┈ ⋯ ┈┈┈ 𝜗𝜚 ┈┈┈ ⋯ ┈┈┈𝜗𝜚.⋆
