In the released video, the interviewer asked Nam Joo Hyuk what his favorite motivational quote was in Twenty-Five Twenty-One. He answered, ŌĆ£I didnŌĆÖt know when we were filming, but after it was aired, I found that there are many lines that people relate to. There was Baek Yi JinŌĆÖs line that goes, ŌĆśGravity is constant regardless of any expectation.ŌĆÖ I like the line.ŌĆØ Then he was asked what time he would choose to go back if he were to go back in time. He replied, ŌĆ£I would like to go back to when I was 25. 21 would be too young. And I think 25 would be just right. I remember I had a lot of fun, but I also worried about a lot of things when I was 25. So I would like to go back to 25 years old me.ŌĆØ
He also revealed that he still likes to throw dad jokes here and there every once in a while. He explained, ŌĆ£Now itŌĆÖs more like I say those jokes before I know it rather than to say that I like them. I find the other personŌĆÖs reaction very funny. I think itŌĆÖs really for my own pleasure. I try not to let go of any chances that I can use my dad jokes.ŌĆØ The actor closed off his interview with a heartfelt message to people in their 20s. ŌĆ£Just as a young person living in the same 20s, I realized that life does not go as planned. Hard work pays off. Everything is not easy. There are times when things just work out easily. But I think thatŌĆÖs a trap because life is long. You have to be careful, especially at times like that, and work harder and live your life to the full so that you can put down all your worries and take a break and relax,ŌĆØ he shared. Source (1)
