"I always liked to write simultaneously from elementary school students," said Seo Ji Eum, a lyricist who met at Seosomun in Seoul. "I started to write lyrics in earnest, but I became more focused on pronunciation." “I’ve got a long story crumpled into the lyrics, and it’s easy to melt into the lyrics, and I usually hang a fishing rod in one place when I meet friends or watch TV. It’s always a new word to get ready to catch, and that’s the biggest asset I have.”

It was important to listen to the recorded files of guide vocals from each agency or composer. “The answers are hidden in them. The composer’s intentions and the color of the song are in them, so you have to read them well. The word “twinkle” of the Girls’ Generation Tatticer or “dumb” of the Red Velvet was in that part. “Crown” and “Achu” also found words that could be as close to the guide pronunciation as possible, but that sounds like meaningless words, but they get hints.”
