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 hits the upload button and leans back in his chair, notifications start chiming one after another.
Despite the late hour, comments pile up quickly as if people had been waiting.
Sungjun, what is this song...
It sounds even better in the middle of the night.
This track is exceptionally warm, isn't it?
It feels like there's a specific person in the lyrics.
Did you make this thinking about that person again?
Sungjun skims through the comments, his hand pausing at the last one.
After staring at the screen for a moment, he flips his phone over without leaving a reply.
That person was in this song, too.
And no one knew who it was.
