Koito Yuu just began her first year in high school but still hesitates to respond to a confession she received from her friend during middle school graduation. Unlike the sparkly and bright love she hears in music and reads in books, his confession did not fill her heart with any emotion.

As Yuu walks to the student council, she stumbles upon Nanami Touko turning down a confession with certainty and kindness. Nanami's confident response that she has no intention of dating anyone sparked Yuu's interest, so she seeks Nanami's advice on how to respond to her own confession. Yuu confides that she already decided to turn him down, explaining how she wanted to fall in love but is unable to as she has never felt what it is like to have someone special.

Nanami comforts Yuu with sympathy for the difficulty of wanting to love but not having someone to fall in love with, and at that moment Yuu's phone rings. Nanami takes Yuu's hand and tells her she only needs to speak from her heart. As Yuu turns down his confession, Nanami's hand still holding hers, a bright new spark was formed.
