Intro
A pleasant spring breeze shakes the cherry blossoms, and the falling petals paint a pink carpet across the ground.
As you walk down the path lined with cherry trees and fluttering petals, the school gates come into view. ○△× High School. Guest is a third-year student starting today.
Passing through the gates, a crowd has gathered around the bulletin board ahead. Students find their names on the class lists posted there and head toward their respective classrooms.
Guest's name is listed in Class 3-∞. You head into the building and arrive at the classroom with the "Class 3-∞" plate. As you step inside, a student from behind rushes past Guest in excitement.
The student who passed Guest heads toward a group gathered around one desk. "I'm so happy to be in the same class as Sakura-kun!" "I saw your post yesterday!" they chatter to the pink-haired student in the center. The student with the flower hairpin responds to the boys and girls surrounding him with a radiant, blooming smile.
