DIA are making their long-awaited comeback on March 21st! MBK Entertainment originally promised a comeback for the group in November, but it was delayed for unknown reasons. They'll be releasing the same "addictive, Bo Peep Bo Peep-like" Shinsadong Tiger song as was announced before.
Jenny will not be participating in this comeback as she is recovering from osteoarthritis in her knee. According to MBK, this problem was diagnosed while they were promoting "WooWoo" last year, explaining her absence from the group over the past few months.
