Actor Kim Soo Hyun transformed into a 'professor' with a pair of glasses.

Recently, Kim Soo Hyun lost his Korean traditional costume to pull off the sporty look for a photo shoot.

In the released photo, Kim Soo Hyun appears as if he is ready to go hiking in his red windbreaker and fedora. The added brown glass makes him appear like a 'professor' who is ready to go study the mountain.

Internet users who saw the photo commented, "Those glasses kind of make him look like Bae Young Joon," "Even his glasses looks custom made," "He looks like a young professor.”
