On July 28, JYJ member Kim Jaejoong posted a photo on his Twitter while on set of MBC‘s drama, “Dr. Jin.” He commented the photo saying, “Father Hansoo,” implying a word play for “hansoo,” which means “moves,” or “to be cut above.”

The meaning of the title is explained in this goofy photo. The photo shows Kim Jaejoong wielding a sword over his on-screen father, actor Kim Eung Soo, who retaliates by grabbing the sword with one hand. While Kim Eung Soo is holding the sword high above his head with one hand, Kim Jaejoong is charismatically gripping the sword on the other end. However, this seemingly serious photo is comical due to Kim Jaejoong’s surprised look and their poses.

Upon seeing this photo, netizens responded by saying, “The impression of wielding a sword,” “Father Hansoo has moves,” and “Both of them are very adorable.”
