Leessang Company stated to the press, "The end-of-the-year concert was planned in the beginning of the year and we gave a lot of thought about Gil's appearance. After much deliberation, the agency believed that it was his duty to make an official apology to his fans on a formal stage setting, and Gil also decided to go on stage."�

The agency also revealed that for the past eight months, Gil focused on his music and, although he felt burdened to be back on stage,�he decided that it was only right to apologize to his fans who have been waiting for his official statement.�

Meanwhile, Gil was caught for drinking and driving this past April and had his license revoked. In addition, the singer also took time off from appearing on 'Infinity Challenge' to self-reflect.
