The JYP head visited the set of 'Unnies' Slam Dunk' once again to oversee the music recording process, giving pointers and advice for the cast members. When it was Tiffany's turn to record, a smile immediately creeped up J.Y. Park's face. Unsurprisingly, J.Y. Park spared Tiffany no compliments, telling her that she was much improved than before. Tiffany joked lightheartedly, "Did I gain some air [in my singing]?" referring to J.Y. Park's famous method of using a 'half air half noise' sound. 

Though J.Y. Park was completely satisfied with Tiffany's singing, Tiffany herself seemed disappointed in herself as she wasn't in the best condition. However, the end result was much better than what the both of them expected, mostly thanks to Tiffany's insistence on recording her parts over and over again. 

Good work, Tiffany!
