The group released a teaser image through NCT Dream's official Instagram, and it's a bunch of separate pictures assembled to create one giant collage. It's a very bright and bubbly picture, bursting with neon colors and sweets. We also learn the name of one NCT Dream member, and it looks like it's Jisung! The official Instagram account, which includes the term "Chewing Gum," possibly alludes to the name of the song that is to be released.
We'll just have to wait to find out!
