Actor Choi Sung-won shed tears while recalling the difficult times he endured during his battle with leukemia.
On the program 'Happy Together - Because I'm Not Alone' airing on the 7th on KBS 2TV, close friends known as "20-year companions" Choi Sung-won, Park Hae-soo, Im Chul-soo, and Park Jae-yoon will appear.
In a preview released ahead of the broadcast, Choi Sung-won is shown reminiscing about his past battle with leukemia.
Host Jang Hang-jun cautiously brought up the topic, saying, "There were news reports that Choi Sung-won fell ill while his work was at its peak." In response, Choi Sung-won shared, "I got sick in 2016, and it also recurred afterward. It was extremely difficult," revealing the pain he experienced at the time.
Choi Sung-won, who had previously said he didn't even want to recall those days, eventually reddened his eyes, conveying a sense of sorrow.
Im Chul-soo, who has watched over him for a long time, also shared his feelings at the time, saying, "I was seriously shocked. I cried a lot while walking that day." Park Hae-soo expressed support for his friend, stating, "I had faith that he would recover even better and more healthily."
Meanwhile, Choi Sung-won received a diagnosis of acute leukemia in 2016 and temporarily halted his activities. After completing treatment, he returned in 2018, but the illness recurred two years later, leading him to resume his battle with the disease. Having undergone bone marrow transplant surgery, he was declared cured after a long two-year treatment period.
