Jaejoong worried fans with his photo from the hospital.

He posted a selfie while he was hospitalized and wrote, "It hasn't been long since the new year, and I've already born a small misfortune to prevent me from a bigger one later on. But don't worry! I'm going to recover soon, and the concert later this month will go on as planned so I will come back healthily. Everyone, be healthy and happy new year!" The post was posted without an explanation to how he got hurt, but it looks like he's at least in good spirits.

Get well soon, Jaejoong!
