On May 22, 2023 KST, Stray Kids posted the teaser of their song "Youtiful," which will be officially released on June 2, as a B-Side track of their album "5-STAR." The lyrics were written by the group's leader, Bang Chan.

The track "Youtiful", a clever fusion of "You" and "Beautiful", delivers a powerful message of self-love, underscoring the importance of taking pride in one's individuality and embracing their personal beauty. Its lyrics delve into this concept, articulating how self-doubt can often cloud our perception of our own worth, yet we remain perfect in the eyes of others.

The group lends an intimate touch to the song, reflecting on shared experiences of struggle and emptiness through lines such as, "I know that feeling too, I've been inside the dark. I've never been so empty, hopeless". However, they promptly shift the narrative towards hope, assuring listeners that they are not alone - "It isn't true, 'cause know that all the stars are by your side."

"Youtiful" is more than just a song; it's an uplifting anthem that can bring solace and inspire resilience, especially for those grappling with challenging circumstances or personal adversity. Its encouraging message has the power to turn around one's day, acting as a beacon of light amid any prevailing darkness.
