It's #KpopMonday, and for the #SadSong theme: IU and Seo Taiji's Sogyeokdong (μ격λ): https://www.youtube.com/watch?v=GHu39FEFIks
Melancholy lyrics about memory and disappearance, and an MV with a cute story of a boy and a girl, but filled with dread just out of sight...
The MV is set in a specific historical context of South Korea in the 1980s, from Seo Taiji's childhood: https://askakorean.blogspot.com/2014/10/history-behind-seo-taijis-sogyeokdong.html
The Seo Taiji MV version makes the story even more clear: https://www.youtube.com/watch?v=WH0iiU0cv00
