NCT Dream has dropped a teaser image for "My First and Last"!

The photo has a lot in it, including what looks like lyrics in Korean, English, and Chinese. It looks like they're talking about their first and last love, and to keep in the theme of school, the teaser is on a chalkboard. The photo was tweeted with the caption, "Where you can find NCT Dream'.
