It’s a wedding song that can be taken not only as a love song between a man and a woman, but also as a song for sisters.

There are various ways to interpret the bouquet in the title, but the track is filled with happiness and affection, even evoking the image of an older sister tossing her bouquet to her younger sister.

AI – Story

When you listen to AI’s famous song “Story,” many of you probably think of the movie Big Hero 6.

That’s because the English version of the song was used as the ending theme for the Japanese release of Big Hero 6! Although it’s not a song themed around sisters, AI has said she watched Big Hero 6 while thinking about her younger sister and ended up in tears.

While the song can be heard as a love song, once you know that story, you start to feel like she might be singing about her sister.

It’s a highly recommended track to dedicate to a beloved sister!
