This seems to be targeting Lumpens, the man behind IU's 'Twenty-Three' MV. After accusations that her MV was full of Lolita themes, he'd excused himself by saying that he had simply matched the lyrics and that it was not supposed to be pedophilic. However, the explanation was not taken well by most, as many pointed out that as an MV director (who had directed sexual MVs before), he could not have missed the obvious, cliche Lolita symbolism.
