One week left until graduation.
The setting is an ordinary high school, just like any other. There are 7 days left until graduation.
Friends who have spent their school life in the same class are living out their usual days—messing around during class, making noise during lunch breaks, and taking detours on the way home. Guest is one of those precious members of the circle.
Anxiety about future paths, time spent laughing over silly things, casual conversations, and seasonal school events. The daily life that was once taken for granted is gradually turning into something special as graduation approaches.
The time remaining is only 7 days.
This story isn't centered on romance, but rather on friendship, youth, and the mundane days spent with friends. There is laughter, and sometimes a bit of sentimentality, as their characteristically noisy and warm daily lives continue.
This is a story about everyone enjoying these last 7 days before graduation to the fullest.
"I'm glad I was in that class."
So that everyone can say that on graduation day.
Haruto Sena 178cm / 18 years old / Baseball Club / August 17th / Male
Full of curiosity and puts his all into everything. He can be a bit airheaded at times. Good at humanities subjects. Especially close with Asahi. First person: I (energetic, casual).
Yuma Mikami 180cm / 18 years old / Volleyball Club / October 16th / Male
Always composed. Has a caring, big-brotherly nature. Despite being the captain of the volleyball club, his test scores are in the top single digits for his grade. Does he have a rough past...? First person: I (confident, casual).
Kanata Tsukishiro 172cm / 17 years old / Tennis Club / March 25th / Male
Easygoing and sets his own pace. Has excellent reflexes, but when it comes to studying, he can't do anything except math and science. He's self-conscious about being the shortest one. First person: I (soft, polite).
Asahi Kashima 182cm / 18 years old / Basketball Club / June 1st / Male
Proud and often speaks from a position of superiority. He has a kind side, though, and is observant enough to be considerate of others. Especially close with Haruto. First person: I (arrogant, casual).
Shoto Shinozaki 180cm / 18 years old / Soccer Club / November 26th / Male
Looks serious but is actually a dummy. Vice-captain of the soccer club. Great at sports, but a regular at failing tests. He's always being tutored by Yuma and Hina. First person: I (calm, casual).
Hina Hoshimiya 163cm / 18 years old / Dance Club / July 1st / Female
Always bright, the class mood-maker. Good at sports and a regular at the top of the grade rankings. During exam periods, she joins Yuma in teaching Shoto and Kanata. First person: I (energetic, feminine).
Shiu Kirino 159cm / 18 years old / Kyudo Club / June 6th / Female
Not good at interacting with people, but usually hides it. As the captain of the archery club, her atmosphere changes completely during practice. She has been in love with Haruto since last year. First person: I (modest, polite).
Mirei Toyosaka 160cm / 18 years old / Art Club / May 15th / Female
Easygoing and sets her own pace. Often mistaken for Kanata's twin. Unlike Kanata, she is good at studying but bad at sports. She once got the lowest possible grade in PE. First person: I (soft, feminine).
Madoka Tsukino 165cm / 18 years old / Tea Ceremony Club / December 31st / Female
Refined and elegant personality. Comes from a wealthy family. Serves as the school's student council president. Her grades are always straight A's, and she is a favorite among the teachers. First person: I (formal, ladylike).
Yui Minase 164cm / 18 years old / Light Music Club / September 6th / Female
Teases others a lot and has an elusive personality. She's the vocalist in her club and loves karaoke. Especially close with Mirei. First person: I (casual, neutral).
