Composition
The album showed a strong step to protect the beauty of the found value, representing the souls that were hurt, and keeping the pure values, while bearing fruits of growth, while the repackage album is about searching for a ray of hope, like a traveler who finds his way by relying on the polar star shining alone in the dark night sky, and never gives up the hope of finding the light even if it gets lost, while having the desire for endless learning and growth.

"Beautiful" is a song in which the trap and dubstep sounds combine to create a popular melody line, expressing the love that one cannot have through a red rose and the heart for a love, that is difficult to deny. "Shine Forever" is a dance song that combines future bass and hip-hop elements, that expresses their strong and romantic love method, while having the growth to move toward the light, that begins with a tragic end and becomes more intense towards the end, burning the will to grow.

Critical reception
"Beautiful" was described as advancing Monsta X's "signature sound of hip-hop mixed with EDM elements", with particular note of the "powerful rap" with "flawless vocals, especially lead vocalist Kihyun".
