Lee Jong Suk gave four different looks to swoon over, showing his transformation as he crosses the border from a doctor in North Korea to South Korea.

A rep from the drama's production company Aura Media stated, "We couldn't take our eyes off the way Lee Jong Suk brought his changing character Park Hoon to life on set. It will be fun to watch the transformation with your own eyes on 'Doctor Stranger'... We firmly believe that you will be able to rediscover [the charms of] Lee Jong Suk who doesn't miss a single detail and perfectly acts out his role."

'Doctor Stranger', directed by 'City Hunter' and 'The Sun of My Master's PD Jin Hyuk, will portray the story of a genius North Korean defector, Dr. Park Hoon (Lee Jong Suk), who enters South Korea's top hospital and adjusts to life as an outsider at his workplace.

The drama will premiere on May 5!
