I want to stretch myself. Another reason why I'm so fortunate is that this is a drama and I've been brought up in comedy.

I was more into music, before I got into college. In high school, I used to play guitar and sing. I did a lot of that. But, when I graduated and went to college, I remember my freshman year and this girl from across the hall, who is one of my good friends to this day, had a brother who was in the school improv team. We went to go watch a show and it blew my face off.

I was a psych major in college and I actually owned two white lab rats. I had to train them and I took them home so that's just kind of missing for me.

I remember the first day I got there, they started the take and after four takes I was on the ground, on my back, with a banana and a Twizzler in my hand, and my face was green, and they said, "You can't get back on set for another 30 minutes." That was a, "Welcome to Atlanta," and that put everything in perspective.

Maybe it's a cultural thing, being Korean, but my first reflex has always been to exude humility - but it doesn't help you in acting. For acting, humility isn't the best thing. It'll weaken your work.

Whatever I lack in size and strength and speed, I kind of make up for in being grittier. When it comes to something like basketball I'm definitely not the best guy on the court, but I love elbowing and pushing people out or boxing them out.

The most fun thing about doing the show is that, as a nerd, the fun has been in learning and having it be like a grad school for me, every day. Every moment is a new experience. Every conversation is a new gain.
