[OPENING] Stray Kids (Back Door) - The upbeat and energetic song which shows Stray Kids' festival vibes. The point of the lyrics is "authorized personnel only", which go with the extravagant performance. [MY IDOL DIARIES] E'LAST (Tears Of Chaos) - The follow-up to their debut song 'Swear'. It holds the image of betrayal, misunderstanding, brainwashing, and being awakened. It's about the memories and sadness of one who loses oneself. [CLOSING] NCT U (From Home) - The NCT members who all came together with the dream of becoming a 'singer', look back on their times, and talk as reliable friends and family about unfolding their dreams.
