In fall 2011, Kim signed on to star in "Me Too, Flower!" opposite Lee Ji-ah. But on the first day of filming on October 4, he was injured when the moped he was riding malfunctioned and accidentally accelerated. After being diagnosed with a dislocated shoulder, bone fracture and torn ligaments and cartilage, he withdrew from the drama and was replaced by Yoon Shi-yoon. Kim cancelled all entertainment activities for ten months and underwent rehabilitation under Dr. Na Young-mu (well known as the doctor of figure skater Yuna Kim), eventually making a full recovery.
