The Moment I Heard That Song

It's cheerful, yet a little sad.
It's a heartbreak song that combines J-pop, sparkly pop, and emo pop, depicting the moment when you remember an unforgettable "you."
You suddenly hear "your favorite song" playing in the street.
In that moment, your stagnant feelings start moving again.
You want to move forward, but you also want to remember just one more time.
I put those feelings into the song.
