Ivy shared on the July 1st broadcast of 'Beatles Code 2', "2PM's fans responded with things like 'Why were you all up on my oppa?' After the performance, my mini-homepage got terrorized. Hundred thousands flooded my mini-homepage." 

When the MCs said, "It seems like Nichkhun would have apologized about that," The songstress remarked, "No, he didn't apologize." Hearing this, MC Tak Jae Hoon teased, "You should have just really bitten his neck."
