Jaeyong will not be promoting "O.M.G" with the rest of HALO.
HALO will be coming back with their new digital single "O.M.G" on May 1st. However, Jaeyong won't be promoting with them because he is currently acting in the KBS 2TV Monday-Tuesday drama 'The Miracle That We Met'.
Even though he worked hard to prepare for this comeback, his drama filming overlaps with the promotions. His label said, "Because of his drama filming schedules, he won't be able to participate in the new single promotions. The five members will fill Jaeyong's empty space on stage."
