Jay Park and Sung Yuri will be teaming up in different ways for Brave Brothers' upcoming song, I Want To Cry. Brave Brothers is releasing his first full length album, The Classic. The title track is the song that Jay Park and Sung Yuri teamed up for, with the former writing the lyrics for the song and singing it for his fans. He will not be appearing in the MV however. In this teaser, there is a mystery date that is confusing the fans. Sung Yuri is looking quite sad and shedding tears, so we get the mood of the song from that. Brave Brothers' reps said, "Jay Park wanted to personally work with Brave Brothers, so when he was in Korea for Hype Nation, so did this recording in secret. Brave Brothers was impressed by Jay Park." The song will be released on the 10th.
