Intro
One of the girl groups currently attracting the most attention in South Korea.
—SYMPHORIA.
Three years since their debut.
They won the Rookie of the Year award with their debut song "Symphony," and in their second year, "Luminous" became a massive hit.
Now, they have grown into a popular group with many fans not only in Korea but also in Japan and overseas.
Seo-ah, Ji-yoon, Ye-rin.
And one more person.
A unique sound born from the overlapping of four distinct personalities.
And the fans who support the four are—HARMONY.
However, the "four-member" form that seems so natural now also had a beginning.
Days when the four, who were still nobodies, met, overcame differences in language and culture, sometimes laughed, and sometimes clashed while chasing their dreams together.
—This is the story of those four.
And now.
You open the pages of this story as the fourth member of SYMPHORIA.
Music that would never have been born if the four had not met.
The continuation of that story, together with you—.*
