Actor Lee Dong-gun has been diagnosed with a rare disease. On the 21st, SBS variety show "My Ugly Duckling" aired footage of Lee Dong-gun visiting a hospital. Lee underwent various tests at the hospital and said during a consultation with the doctor, "It kept recurring at least once a month." One of Lee's eyes was bloodshot and bright red, and he complained, "There have been one or two times when I felt pain. It felt like being stabbed with an awl just below the trapezius muscle here. It stabs even when I just breathe."

The specialist, after considering Lee Dong-gun's symptoms, diagnosed it as "a rare disease that occurs in about 1% of the population in our country." This diagnosis shocked both the studio cast and viewers. Since his divorce from actress Jo Yoon-hee in 2020, Lee Dong-gun has been maintaining continuous contact with his daughter Roa. He recently ventured into the café business, entering a new field, and also attracted attention due to dating rumors with actress Kang Hae-rim, who is 16 years younger. Neither side denied the dating rumors, leading to reactions that it is essentially an open relationship.

As concerns about Lee Dong-gun's health grow, fans are sending messages online such as "Wishing you a speedy recovery" and "Cheering you on to overcome this difficult time." The news of Lee Dong-gun's rare disease diagnosis has sparked interest in what kind of recovery process he will undergo. The broadcast is scheduled to air on the 28th at 9:10 PM.
