It is a song about the memories of girls who are remembered as fireworks that embroider the black sky.

The song was once again completed by composer Stephenie, who worked on OH MY GIRL's previous "Secret Garden," and Swedish hit songwriter Caroline Gustavson, who worked on Girls' Generation's songs.

The girls' memories are unraveled with various emotions such as happiness, excitement, sadness, and waiting, and the dynamic and beautiful melody is impressive.

Also, the balance of synthesizer sound and acoustic unplugged instruments is combined with OH MY GIRL's emotional vocals, drawing attention by expressing them in dynamic and universal colors.

Completed with the lyrics and composition of 'WOOZI', the powerful base riff, unique composition and arrangement of the song are impressive.

With the outstanding singing of the vocal unit, the rap of the hip-hop unit, and the choreography of the performance unit leader 'Hoshi', the song was completed with the cheerfulness and power of the 13 members at the same time.

The song, "Mansae" is an interesting story about a shy muttering to oneself, "Hey, girl!" and expressing the boy's love with a witty emotion.

The song has an attractive retro sound. There is no standard set by the world, and it means that even if the "me" that others see and the "me" that I see are different, I will respect and cherish the "me" that remains unchanged. Mamamoo's bold and bright voice reminds us once again that loving and caring for ourselves is itself for "I."

In the music video, the vivid contrasting vivid colors, the confident attitude of the members of MAMAMOO, and the Athletic look, which further highlights the healthy charm, are reminiscent of a fashion film. Minimal sets, lights, and group dance in them make trendy emotions even stronger.

It is a refreshing tropical house genre-based R&B song that begins with a lyrical arpeggio leaf, and it mesmerizes the ears with SHINee's sophisticated harmony and appealing voice on a bouncy groovy beat. In the lyrics, numbers (one, two, three, four/one, two, three, four) and Korean (a, me, da, la) are solved like four-line poems, and the chorus, which gradually compares lovers to words, sentences, and languages, adds to the fun of listening.

It is a medium tempo R&B song with a lyrical atmosphere, with a deep echoing electric piano melody, changing rhythm to a hopeful atmosphere, and the chant of the second half of the song, and SHINee members participated in the lyrics with a heart for Jong-hyun, expressing their feelings with a message.

The music video shows those who escape oppression and seek true happiness. A futuristic classroom likely to appear in SF movies. Medicine must control one's thoughts and wear a prison uniform-like costume that ignores one's individuality. BTS escapes against forces that inject a one-size-fits-all mentality. A set of desert with huge fingers through the hard ground symbolizes the struggle for escape. BTS also included a message in the choreography of "N.O" to complete a performance with a story. The performance, which is at odds with dancers reminiscent of the riot squad, offers many attractions. In order to revive the magnificent string of "N.O", about 30 orchestra members visited the filming site and performed live performances. The scene with them and BTS is selected as the best scene in the music video.

No one can live my life for me, nor can I put off my dream any longer.

After all, living the life I want at this time of the day is truly happiness.

BTS is [O!]RUL8,2?] (Oh! Are You Late, Too?) delivers the message 'You must find your own happiness and life before it's too late.

It gives a lesson to the world that forces misfortune through straightforward lyrics that openly reveal reality.

Students raised with just a study machine without time to think about the future. The reality is that classmates do not share friendships, but rather that they are rivals who have to step on. BTS sings of the scars and misfortunes that such a bleak life has left for teenagers.

It tells the story of an indescribable thirst and longing for a powerful unknown object, even in spite of confusion.

It gives you tension and pleasure as if you have read a mystery novel, while at the same time feeling unrealistic like a calm burning blue flame.
