Lee Jong Suk revealed a picture in a school uniform.

Today, Lee Jong Suk posted on his me2day, "It's late. I should sleep. When will today end? Cheer up, you guys" along with a picture.

In the picture, Lee Jong Suk is in a school uniform, smiling at the camera. Around him are fellow casts of KBS drama "School 2013," 5dolls' Hyoyoung, Kim Young Choon, Lee Ji Hoon, and Kwak Jung Wook, making unique and silly poses.

Internet users who saw this commented, "They all look close to each other unlike in the drama," "He's close to Kwak Jung Wook in real life," and "They look so good in school uniforms."
