'The Glory' actor Park Sung Hoon says the hardest part of playing Jeon Jae Joon in the show was that he had to swear a lot when he is not used to cussing. 

On March 10th, the highly anticipated part II of 'The Glory' was released on Netflix. Following the reveal, Park Sung Hoon's latest interview clip garnered attention coupled with his scenes showing him fluently cursing. 

In his interview with Harper's BAZAAR Korea on March 6th, he shared that the hardest part of playing Jeon Jae Joon was he had to swear when he is not used to swearing. He also said the time when he had to shoot a winter scene in the middle of the summer was really difficult because he was profusely sweating. The relevant part starts at the 3:05 mark in the video above.

But in the show, he swears so naturally, which impressed many viewers coupled with his earlier interview. Check out the snippet from 'The Glory' below.
