Se7en returns! The singer and actor is scheduled to be released from the military on December 28. He was originally supposed to leave on December 18, but his ten days serving in military jail delayed the date. 

Last year, he and other celebrities left their assigned dorms without permission and visited a massage parlor. They violated the rules and, in turn, were sentenced to a certain amount of jail time.

The Goong S actor's contract with YG Entertainment expired while he served his country, so his future schedule is unknown. Nonetheless, his name still appears on YG's list, so there is hope that he may sign another contract.
