Seventeen's younger brother group TWS is increasing anticipation for their debut album 'Sparkling Blue' with new teaser photos.

On January 9 at midnight KST, the upcoming boy group released a new set of 'lucky ver.' teaser photos through their social media.

In contrast to the refreshing 'Sparkling' version teasers with a background filled with blue skies and sea, the 'Lucky' version captivates with a blend of rain-soaked ground, umbrellas, and the members' emotional moods.

In the group photo, TWS's unpretentious charm is revealed as they stand side by side under an umbrella against a wall, expressing their individual personalities in a city-boy look that exudes the naturalness of youth. The greenery of the trees and the boyish charm of TWS harmonize to create an atmospheric vibe.
