Photos of Super Junior's Choi Si Won crossing the streets of Apgujong dressed very casually have surfaced on the internet. Although he looked comfortable in a grey shirt and casual sweats, he looked good enough to step on the set of a photo shoot. His outfit could not mask his perfect physique, which garnered the attention of the people walking by. Choi Si Won is currently cast in KBS2's 'Poseidon', playing the role of Kim Sun Woo and impressing viewers with his natural acting abilities. The final episode airs on the 8th.
