Behind-the-scene photos of Lee Kwang Soo filming the last two episodes of the drama 'Nice Guy' have been revealed.

Most of the photos show Lee Kwang Soo reviewing the script in a serious manner, while one photo captured Lee Kwang Soo and his contagious smile.

With only two episodes left in the drama, Lee Kwang Soo, who plays the character Kang Maru's (Song Joong Ki) best friend, has been stirring some emotion among viewers.

His character Park Jae Gil is the only one who knows of Kang Maru's illness and is in constant pain for his best friend. At one point, Jae Gil lies in front of the door and tells Maru to step on him while leaving if he isn't going to receive treatment. However, behind the scenes, Kwang Soo created laughter as he actually lied down on the floor while practicing his script.

Viewer ratings for the drama also increased when Jae Gil made a tear-jerking visit to his father's grave and prayed for his best friend's life.

Netizens commented, "Nice guy Kwang Soo is so lovable", "Cute Kwang Soo who doesn't let go of the script even while lying down", and "His laugh makes me smile too~".
