JYJ's Jaejoong recently stunned his co-stars and production crew by pulling off an impressive presentation scene for SBS's 'Protect the Boss'. Considered as the 'prince of the financial world', Jaejoong plays the role of the director of headquarters, 'Cha Moo Won'. Mid-July, he had to record a scene where his character was to give a professional presentation during a meeting. Although the script was filled with professional terms that he wasn't familiar with, Jaejoong spent every spare moment he had to pick apart and analyze each term in order to better understand his script. What surprised staff the most was that he didn't make one NG once the cue sign was made from PD Son Jung Hyun. One representative said, "Jaejoong received a round of applause from staff after completing his world tour, which he directed, from April through June. That same passion and sincerity is being reflected in this drama." 'Protect the Boss' will begin airing on August 3rd. [gallery] Source + Photos: OSEN via Nate
