Ji Soo continued, "I was limping my leg before I went to the hospital. It was so painful; it was the hardest time in my life. But when I think about it now, time flew by, and I wonder if I was ever hurt. The human body amazes me." 

The actor also talked about his drama, 'Fantastic', which was still filming during his sudden hospitalization. Ji Soo said, "The scriptwriter had a difficult time too. They had to take out lines that were already set. The directors and staff worried about me a lot, and I was also very sorry. However, amazingly enough, I was able to participate in filming and make it look like I was walking thanks to [the staff's] consideration. At times, they just filmed bust cuts because I had a cast on my leg."

Stay healthy, Ji Soo!
