This article is basically talking about the BTS video released by MBC today, so I’ll just translate the part about SeungGi’s greeting.
Lee Seung Gi introduced Gu Family Secret, “It’s been a while since my last drama, and this is the first sageuk challenge of my life. The genre is martial arts action drama.” He then said confidently, “Kang Eun Kyung writer-nim’s solid story with an element of fantasy, of me being a half-human-half-beast, meets Shin Woo Chul PD-nim who’s considered to be one of the best directors in the country, I have no doubt this will be a good drama.”
Lee Seung Gi also made a request, “I will greet everyone with a good drama and good acting. I would like to ask for your support.”
