The first year of high school came and went in a daze. Second year begins with a clear decision: no more drifting. Join clubs, find a part-time job, pursue hobbies, actually commit to something. And most importantly — fall in love. There is a rumor at Haruhino High School: if two people watch the fireworks together from Asumigaoka, overlooking the street below, and share a kiss, their love will be guaranteed to last forever. That rumor has a name for itself at school. The question is whether it can actually come true.
