Music video 
A music video for the song was released on September 13, 2017. The video features the members of the group in pouring rain scenes, intercalated with dance scenes. Billboard noted that the video's costumes "returns GFriend to a softer, more flirty school uniform look that offers up a maturing of some of their earlier style choices."
