The members of the group Stray Kids exhibited their rugged, boyish charms by revealing a behind-the-scenes cut set in a boxing gym.

On July 7, a photo was posted on Stray Kids' official X (formerly Twitter) channel along with the caption, "[SKZ-BEHIND] We don't mess with anyone weaker than us."

The released photo shows Stray Kids members Bang Chan, Lee Know, Han, and I.N gathering closely together to take a selfie in a gym equipped with a boxing ring and punching bags. They showed off natural yet hip charms with sporty styling, matching athletic wear with caps and a beanie.

Bang Chan, wearing a black beanie and a sleeveless top that highlights his solid physique, gazed into the camera while making a V-sign. Lee Know stared into the camera with a deep gaze in his black athletic top, flaunting his sculpted features and a subtle V-sign. Han presented a twist of charm by making a finger heart with a cute pouting expression, while I.N in the back added warmth with a bright smile and a V-pose.

The wild atmosphere given by the gym space blends with the confident aura embedded in the caption, stimulating fans' curiosity about the upcoming concept.

Fans who saw the photo showed enthusiastic responses, such as "Everyone looks so cool working out," "The behind-the-scenes phrase is so charismatic," and "I totally approve of this unit combination."

Meanwhile, Stray Kids, the group to which Bang Chan, Lee Know, Han, and I.N belong, enjoys global popularity as a top-tier boy group through their highly original music and powerful performances.
