BTS has made a comeback with their new song "Boy in Luv", and the group revealed their HOT dance practice video.

On February 16th BTS posted the video to Big Hit Entertainment's official YouTube channel.

In the video, these "Boys in Luv" are shown wearing comfortable sweatpants for their practice. They put on a flawless hip hop dance practice performance. Even though it's just a practice video, they put on perfect facial expression acting that could be aired as part of a music program broadcast, proving that they really are a professional group. Their dance moves go particularly well with the song's hip hop beat.

But the group isn't just all about work, work, work. They know how to have fun as well. The photos posted along with the dance practice video show the members' playful and lively sides, as they piggyback on each other's backs and hold up Vs with their fingers. It reminds the public that despite their professional demeanor, boys will be boys.

BTS' title song "Boy in Luv" is a song about love between teens, and lyrics that are relatable to that age group.

BTS released their 2nd mini album Skool Luv Affair on the 12th, and are currently in the midst of vigorous activities.
