[All] Seventeen Comeback Concept Film with a Dreamy Feel

The second concept film for the 5th regular album 'HAPPY BURSTDAY', which will be released on the 26th, has been revealed!
It's full of a dreamy atmosphere that's different from Seventeen's previous vibes~
You can see the silhouettes of the members and you can feel a slightly chilly atmosphere.
I'm even more curious about what song it will be haha
