J.Y. Park lashes Jessi with harsh criticism on 'Unnies' Slam Dunk'

The JYP head judged the entire crew on how much they have improved upon their performance skills. Out of all the cast members, J.Y. Park was particularly severe in his remarks toward Jessi for forgetting her lyrics. He told her, "Jessi, I don't know if you have enough [time to practice] but your efforts are really lacking. What are we going to do when you can't even memorize the lyrics or the melody?"

In the individual interview portion of the show, J.Y. Park explained that he wasn't as hard on Jessi as he could have been, saying, "I'm most regretful about Jessi. Because there is a difference in ability, I thought I could go more easy on her." 

Jessi seemed to reflect on herself more after J.Y. Park's criticism. She said, "I didn't practice enough. I should have said that I was busy with my other schedules or something. It's entirely my fault."
