“I don’t really draw pictures of the future in my head. I’m obviously curious. However, the future will one day become the present anyway. That’s why I try to live in the moment.”

“I don’t think age has a big meaning. I believe your thirties is just a difference in number. If I had to purposely give it some kind of meaning, I’d say that I have a lot of excitement. I’m looking forward to the projects and people I’ll meet in the future.”

“Although it’s important to take into consideration the opinions of others, I believe you ultimately have to make the best decision yourself. That way, you don’t blame others or have regrets even if the results aren’t great.”

“When I watch the projects of actors I like and respect, I am overwhelmed with emotions mixed with jealousy. In my opinion, my thoughts like ‘Why can’t I act like that? I work hard too, but what do they do to go beyond that? What kind of concerns did they have while filming this scene?’ become the drive that help me work even harder.”

“Besides acting, there’s nothing else I’m greedy for. I tend to be indifferent. If I want to do something, I do it, and I don’t measure or calculate it. I just go with the flow.”

“Whether it’s work or entirely personal matters, you need time to take one step back and see things from a wider perspective. In the past, I felt a lot of pressure regarding filming sets, but when I thought about it while resting, it was a place I missed and was thankful for. Where I also have many happy memories.”

“During my hiatus while I’m serving in the military, I’ll have time to look back on myself and think.”
