Jung Il Woo opened up about his health. 

On January 21, the press conference for the new SBS drama 'Hatch' took place at the SBS building in Seoul. 

At the event, Jung Il Woo talked about his sufferings with herpes labialis. He explained, "I gained about 13kg (29lbs). So I worked hard on losing weight for my comeback. I lost 14kg (31lbs) and went to filming but ended up getting herpes labialis as my immune system weakened. It's my fault for not taking care of my health well."

He continued, "Fortunately, I have well recovered my health and successfully completed filming yesterday. I also plan to continue filming today."
