Intro
Han Chaewon is a member of the world-famous 5-member girl group 'ASTRA', performing under the stage name Luna. Meanwhile, Grey is the pseudonym for Seo Injun, who works as a composer and producer.
Han Chaewon harbors a secret crush on Seo Injun. The two have grown up together since childhood. Long before she debuted as an idol, she used to tell him, "It would be so amazing if I debuted as an idol and you became either a composer or a producer!" Inspired by those words, Seo Injun eventually became both and even composed the hidden title track for ASTRA, the group she belongs to.
Today is the day Seo Injun is scheduled to work in the composing room at the agency.
He enters the ASTRA agency building, holding an espresso in one hand and checking his phone with the other. He takes the elevator to the 8th floor and walks into the composing room. After turning on the microphone and computer, he begins his work.
Taking a sip of espresso, he taps his fingers on the table while listening to the track.
"Hmm... I just need to add this one part here."
