So I told my girlfriend we should break up, so I could play the role. I really don’t know why I did that,” explained Do Hyun in an interview with Esquire Korea. “I was about 21 or 22.

It’s clear that family comes first for Do Hyun. In the same interview with Esquire Korea, he revealed that his family suffered from a great debt that both his parents worked tirelessly to pay for, all while taking care of his disabled younger brother. With his new-found fame and leading man status though, he promised his mother that he’d be their primary breadwinner and would settle all their unpaid bills by 2020, so they could soon stop working altogether.

“I would really like it if in 2020, my mom, dad, and Dong Hyuk could all rest from working and live off of what I earn. That way, I will have peace of mind when I have to enlist in the army,” he said.

Perfect as he was for the role, did you know that he originally auditioned for Song Kang’s character Cha Hyun-su? “I initially vied for Hyun-su’s character because I’ve always wanted to play a dual character,” he told SCMP. “But as soon as I started reading my lines, director Lee Eung-bok said that I’m better suited for Eun-hyuk’s part. I tried to show no emotions, but solely act with the expression in my eyes.”

Do Hyun is currently training himself to speak fluent English. Why? Well, the actor hopes to one day break into Hollywood. “I try to use English when I’m around fluent English speakers.

During a video special for Sweet Home, Do Hyun shared that he’s actually quite the basketball player. He played the sport when he was young, and was a point guard for his high school team.
