JYJ’s Kim Jae Joong made his highly anticipated solo debut earlier this year, but it was Kim Jae Joong, the actor, who shined in 2012.

From getting chummy with hallyu heartthrob Song Seung Hun on the set of drama Time Slip Dr. Jin to getting dangerously close to actress Song Ji Hyo in The Jackal is Coming, the acting bug bit Kim Jae Joong hard in 2012.

When he wasn′t getting face time on screen, Kim Jae Joong was meeting with his fans face-to-face through fan meetings.

But for Kim Jae Joong′s most loyal fans, Twitter proved to be the place to get daily updates straight from star – well, before someone hacked into his account, that is, leading Kim Jae Joong to retire from the social networking website.

Although it was a devastating day for fans, Kim Jae Joong couldn’t stay away for long, and the resilient idol star was back to his tweeting ways a month later.
