Group 2AM's Changmin revealed a picture of Jinwoon sleeping.

Changmin posted on his Twitter, "One spring day... feat. 2AM Jinwoon who fell asleep because he's tired," along with a picture.

In the picture, Changmin is posing for the camera with Jinwoon sleeping in the backseat as his background. He is making a silly smile while Jinwoon is sleeping, not knowing that he is being caught on camera.

Internet users who saw this commented, "This is funny", "Silly Changmin", "Go 2AM", "He must be tired from filming for 'We Got Married" and "Cute Jinwoon."

2AM released their second album, One Spring Day, on March 5.
