DAY6's Young K has revealed the teaser for "Insomnia" for 'Getting Off at Earth' OST.

In the music video teaser, Se Min (played by Ahn Se Min) stares at a classmate, who's been doing the same routine 33 times. "Insomnia" is about wanting to tell someone something that's hard to say, and it drops on October 30 KST.
