Five Fun Facts About Choi Jin Hyuk

Actor Choi Jin Hyuk stole hearts as Lee Seung Gi's monster daddy in "Gu Family Book" and then snagged a prize role as Lee Min Ho's older "perfect" brother in the upcoming drama "The Heirs." Now he also has a role in a new movie, "God's Trick" about a fallen chess player who regains his fame.

Here are a few more things you may want to know about this surprisingly self-conscious actor:

1) He was seriously stressed out about his "Gu Family Book" role as the mountain spirit Wol Ryung.

He worried that his poor acting skills might hurt the drama. He worried so much about the role that the stress caused his hair to fall out.

"I think this drama was the one which made me suffer the most during all my years of acting," said Choi Jin Hyuk. "I liked my character so much that it spurred me to want to do even better."

And his hard work paid off.

"Just acting in two episodes I got 130 times the attention that I got in other roles," he said.

2) He really dislikes his own voice.

"One of the directors on 'Gu Family Book' jokingly called me 'bathhouse' because I sound like the echo that comes back when you speak in a public bathhouse," he said.

And yet he has always wanted to be a singer. Singing was his dream even before he considered becoming an actor. Fortunately, "Gu Family Book" also gave him the opportunity to sing and he contributed the song "Best Wishes To You" to the drama's OST.

3) He currently has no girlfriend but he dated actress Son Eun Suh, whom he met when they appeared together on the drama "My Daughter, The Flower." The couple dated for nine months, breaking up earlier this year. They remain good friends.

4) He has described his ideal woman as having a B blood type. He swears that he does not have a great personality. As a result, he says he does not find it easy to get close to women but when he manages to, he "goes crazy in love."

5) The actor, whose debut was launched after winning the grand prize on a KBS reality talent show "Survival Star Audition," had his first drama role in "It's Okay Daddy's Girl." You can also see him in "Ms. Panda and the Hedgehog," "Pasta" and "I Need Romance."
