New SBS drama 'Daebak's producer revealed why Jang Geun Suk will not be wearing a mustache. 

'Daebak' is a fictional historical drama, which means all the male characters are expected to have a mustache to follow the style of the era. The director revealed that even Yeo Jin Goo will be wearing a mustache in the later episodes of the drama. However, Jang Geun Suk will be an exception.

The director explained, "We did put the mustache on, but then took it off because it was covering Jang Geun Suk's face. We tried on and off several times, and it looked better without it." He also said, "The drama will become too manly if every character has a mustache. Also, Dae Gil is the main character of romance, and it wouldn't fit the public image of Jang Geun Suk."

Overall, Jang Geun Suk's pretty face without the mustache meets the expectations of the viewers and the director. We might not see Jang Geun Suk with a mustache, but Yeo Jin Goo will show a new side with some facial hair on 'Daebak'. 

The premiere of 'Daebak' is set for March 28 KST!
