K-Pop boy band MYNAME will be making their official comeback on July 4 with the song "Baby I'm Sorry."

At midnight on Monday, the group's agency released the official teaser for the new song and video, showing the five members along with actor Yoo Oh-seong and Akiyama Yoshihiro, a Japanese mixed martial arts fighter, in action-packed scenes.

The MYNAME clip is full of bloody fighting scenes and is intended for an adult audience only.

According to the group's agency H2 Media, "Baby I'm Sorry" will be the title track for the group's first mini-album, simply named MYNAME 1 st Mini-Album, scheduled for release tomorrow, July 4.

The album will contain a total of six tracks.

"Baby I'm Sorry" has an electronic beat infused with a piano melody and is about a guy who is apologizing to a loved one.

MYNAME was created by former Fly to the Sky member Hwanhee and debuted in October 2011 with the song "Message."

They have experienced a fair amount of success in Japan where they became acquainted with MMA fighter Akiyama Yoshihiro, who then agreed to be in the "Baby I'm Sorry" music video.
