Group INFINITE revealed the teaser clip of their comeback song "Back".

On July 16, INFINITE revealed the teaser clip of "Back", title song on their second repackage album, on their official homepage.

In the teaser clip, the members of INFINITE show a 180-degree transformation from their royal and dandy image shown in "Last Romeo". In the close-up and image cut, scars and scratches can be seen on the members' face, while Hollywood action-filled scenes dominate the clip.

The melody line, singing "Can you save me" raises expectations for the new song.

Woolim Entertainment stated: "Title song 'Back' is an orchestra pop song never heard before. The members attended an action school for two weeks to film the music video. They pulled off their best action scenes."

Meanwhile, INFINITE will return with their comeback stage on this week's music programs and release their repackage album on July 22.
