“I just do my best every day. If there is just one fan who likes me, I’m gonna do my best for that fan.”

“I’d like to be a hero one day like Spider-Man or Iron Man. I find it fascinating and awesome to be a superhero. As you may know, I’m not a big guy but wanna show “anyone can be anything.” That is one of my favourite phrases in the movie Zootopia.”

“Actually, I have a fear of not appearing authentic. I’m still working on my acting as I haven’t been in this career for long and how to do it well. So I just decided to imagine everything is real whenever I shoot and want to appear genuine.”

“I wanna give a comfort feeling to fans who support me. I’m not so much of an exaggeration type of guy. When I’m acting, if I’m sad, I just wanna express sad emotions. If I’m happy, I wanna express happy emotions, that’s all. So, to whoever watches my movies and dramas, I hope they don’t feel any uncomfortable feelings.”
