Lee Kwang Soo stole the 'Nice Guy' viewers' attention with his sincere tears.

Lee Kwang Soo plays Park Jae Gil, Kang Ma Ru's (Song Joong Ki) loyal friend who is cunning yet passionate, in the KBS 2TV drama. On the 9th episode, Kang Ma Ru was lost and traumatized after the disappearance of Moon Chae Won's character following the car accident.

Park Jae Gil desperately tried to get through to Kang Ma Ru, screaming, "I'm so worried because you're acting like someone who wants to die early. You got through it when Han Jae Hee left. How can you be like this after you've gotten over that difficulty? Don't be like this, Ma Ru." His desperate pleas to his best friend brought tears to viewers' eyes. He also succeeded in cheering up Ma Ru's sister Choco by reenacting a scene from the movie 'Love Actually'.

Viewers seem to approve of his character as they commented, "I cried because of Lee Kwang Soo's tearful acting", "As Choco said, Lee Kwang Soo looks more like Ashton Kutcher", "I think the actual 'Nice Guy' is Jae Gil", and "I realized he's a very good actor".
