July 15 (UPI) -- South Korean boy band BTS is giving a glimpse of its new music video.

The K-pop group released a preview of its video for the song "Normal" on Wednesday.

The "Normal" teaser shows BTS member RM walk into a bathroom that is already crowded with the group's other members standing at the urinals.

BTS will release the full music video Friday.

"Normal" was the second single to debut from BTS' album Arirang, released in March. The album marked the group's comeback following a years-long hiatus for the members to fulfill their mandatory military service in South Korea and pursue their solo careers.

BTS teased the "Normal" video earlier this week by publishing newspaper ads with the headline "BTS Seen in Bathroom Amid Mysterious Late-Night Gathering."

"Questions have been raised following a late-night photos appearing to show all seven BTS members together in what appears to be an unexpected setting. While the gathering itself remains unconfirmed, some have questioned whether the situation was entirely normal. The image has quickly sparked curiosity and speculation," the "article" reads.

BTS consists of RM, Jin, Suga, J-Hope, Jimin, V and Jungkook. The group made its debut in 2013.
