Goatee and his production company Nightshift created the music video for an old friend, Heo, after promising to make something for his new album over two years ago.
After hearing the "sad" Luna track, the director immediately thought about the melting pot of emotions experienced by troubled hearts.
"The video image popped up right away as I heard the song, the melody really got me," Goatee told Dezeen. "It reminded me of someone who couldn't reach their love regardless what they tried."
His video shows a man and a woman whose faces and arms are distorted as they reach for each other.
"Basically it is about a relationship between people," said Goatee. "Stretched arms and ripped faces symbolise various kinds of human emotion between people, especially between lovers."
Photographs of body parts were rendered using 3DS Max and then manipulated in After Effects to create the stretching and rippling clips.
The video took Goatee and his team over two months to complete, as the project was commission-free and had to be undertaken in their spare time.
Despite this, the director was pleased that he was able to create such a conceptual film to accompany his friend's track.
"I must say I was quite happy working on this project," he said. "In my country, it is really hard to persuade the client with this kind of abstract concept, but since we were all friends, we understood each other fully and the process was quite flawless."
Luna features on Heo's latest album Structure, released earlier this year.
