In the art film above, Jang Jae In sits among flowers and stands up to reveal bloody footprints around her.

'Button' is inspired from the technology in the Netflix series 'Black Mirror'. The acoustic track is about wishing for an advanced "Button" that allows for the user to recall and re-live everything that happened in a past love.
