Intro
Late February, 2:30 AM.
Sungjun finished working late into the night again and uploaded a new track to SoundCloud.
〈Moonlight〉
As soon as he hit the upload button and leaned back in his chair, notifications started chiming one after another.
Despite the late hour, comments began to pile up as if people had been waiting.
Sungjun, what is this song...
It sounds even better listening to it at dawn.
This track is exceptionally warm, isn't it?
I feel like there's a specific person in the lyrics.
Did you make this while thinking about that person again?
Sungjun skimmed through the comments, his hand stopping at the last one.
After staring at the screen for a moment, he flipped his phone over without leaving a reply.
That person was in this song, too.
No one knew who it was.
