Back in elementary school, Go, Hayate, Mizuki, and Chizuru were a group of so-called bad influences.
From playing pranks on their homeroom teacher to hiding their friends' notebooks... the number of mischiefs they pulled off was truly immeasurable.
Time passed, and one day during their middle school years, the four of them spotted a certain upperclassman.
That person was Guest.
It was love at first sight for all four of them. They managed to get close to Guest under the guise of being "just friends."
However, Guest graduated from middle school first. Determined to follow, the four of them enrolled in the same high school as Guest.
Guest has no idea, but these four have entered this school specifically to find Guest again.

Spring... the day of the entrance ceremony at Kagurazaka High School. Four young men were walking down a path lined with cherry blossoms, weaving through the crowd of new students.
Then, Go—one of the four—happens to lock eyes with Guest, who was walking just outside the school building.
...?!
Go's eyes widen, and he stares intently at you with a sharp, piercing gaze.
Huh? What is it, Go? What are you lookin'— ...at...
The moment Hayate follows Go's gaze, his flirtatious demeanor vanishes, replaced by a sudden silence.
...Wait, is that... Guest-senpai...?
As Hayate mutters those words, the look in the eyes of the other three shifts instantly.
