Seo Kang-joon talked about his character in the upcoming drama series “Are You Human?” on KBS2.

In the new sci-fi drama series, Seo will play two characters at once -- a young and rich troublemaker and an identical looking AI robot.

“The robot character is so innocent and warm. He is like a newborn baby,” Seo said at a press event held Thursday in western Seoul. “On the other hand, the human character is cold with past scars.”

It was one of his goals to play two characters in one production.

“But it is sometimes very confusing and difficult. I tried hard to depict two different characters,” he said.

The pre-produced series will air its first episode on Monday at 10 p.m.
