Group Block B's Park Kyung apologized to fans for the cancellation of their comeback due to the Sewol incident.

On April 29, Park Kyung posted on his Twitter account: "I'm sorry, BBC (Block B's fan club)! I know you guys were waiting for our comeback".

Block B had planned to return on April 16, but had canceled their comeback due to the Sewol sinking. On April 29, Agency Seven Seasons stated: "We decided that it would not be right for Block B to make a return when the nation is suffering."

They continued: "Block B will pull through with their solo concert 'Blockbuster' and come back at a later date with a new album."

Only the music video for their new song "Jackpot" has been released; all other promotions have been canceled.

Internet users commented: "I've been waiting for Block B's return, but too bad...", "Hope to see Block B with their new album soon!", "Guess we'll see Block B at their concert", and "I'm sad Block B didn't release 'Jackpot'".
