Military service
In April 2008, Choi joined the Korean army for his 26 months military service. After failing two medical tests, he was relieved from his military duty. The main reason was a problem with the sight in his left eye, which was the result of a brain tumor. On June 9, the tumor was finally removed through surgery.
