"Kim Hyun-joong took part in most of the EP's production, including the lyrics, songwriting and arrangement," the company said. Kim plans to print a limited edition of 2,500 copies of the album to sell at an upcoming fan meet-and-greet on Saturday.

The 31-year-old star, who finished his two-year military service in February, was charged for driving while under the influence of alcohol in March.

Kim has also been locked in a legal battle after his ex-girlfriend, identified only by her surname Choi, filed a suit for compensation in April 2015. The plaintiff claimed that she miscarried Kim's child in 2014 after being physically abused by him. (Yonhap)
