During a press conference for Doctor Stranger, Lee Jong Suk and Park Hae Jin could not stop talking about the first impressions they had of each other – basically, it turned out to be a compliment relay. The two act out a fierce competition when wearing white coats, but seem to be very fond of each other off-screen. Watch the press conference below.

Park Hye Jin mentions that he has practiced thoroughly and poured his efforts into erasing Hee Kyung’s image from everyone’s mind. Lee Jong Suk says that he also worked hard to portray an accurate image of a North Korean doctor.
