Byun Wooseok revealed that it took three years for 'Lovely Runner' to go into production. He said, "I play the lead role in this drama, but since I wasn't very well-known, the role was offered to other actors first. That's why it took three years." He continued, "I'm grateful that I was offered the role of Sunjae. As soon as I read the script, I thought to myself, 'I absolutely want to do this.' I had a strong feeling that I should give it a try."
Byun Wooseok's success didn't come overnight. He reflected on the difficult times during his 'nugu' days. He said, "There were times when I got cut off during script readings. It was traumatic. I received a lot of hate and there were times when I had low confidence." He added, "Due to my modeling background, I really love being filmed. However, as I became an actor and constantly getting scolded, I became anxious in front of cameras. I even questioned myself if this job was really meant for me."

Byun Wooseok also said, "People around me didn't say bad things, but I did hear some hurtful comments. Some told me, 'I don't think you'll make it in 4-5 years.' Ironically, things started to work out for me around 4-5 years later." He added, "When I heard those comments, I was more determined to overcome them. I didn't want to be discouraged by those words."
He continued, "Instead of staying idle, I tried to overcome my weaknesses and trauma by experiencing the field. I took on any role, no matter how small, and I think that's how I overcame it."
In an interview with the production team, Byun Wooseok also talked about the difficult times. He confessed, "There was a time when I went to a salon to get my hair done for a character, and then got a call saying, 'Sorry, we can't work together this time.'"
He added, "At that time, a group chat for the actors was created, and I said there, 'I don't think I can do this anymore.' It felt like a punch. My pride was honestly hurt, and I wondered if I would ever make it. I cried to let it out," he said. "But I think those moments made me want to do better and work harder."
