Lee Jae Hoon recently talked about the hit drama series 'Signal' that aired in 2016.

The actor appeared as a special guest in the new episode of tvN's 'You Quiz on the Block' that aired on April 19 and garnered much attention as he talked about the hit drama.

On this day, Yoo Jae Suk mentioned that Lee Jae Hoon had a lot more lines to memorize compared to the other actors and asked what was his secret in being able to memorize all of them. Lee Jae Hoon explained, "I don't think it's a secret but I keep looking at it. Rather than thinking that I am memorizing these lines, I think of it as reading them aloud."

Lee Jae Hoon also shared that he usually doesn't make bloopers for other films or dramas, but he made a lot of bloopers for 'Signal.' He elaborated that he made many mistakes when filming with actress Kim Hye Soo.

He shared, "I think it was the first time I ever experienced this. I would see Kim Hye Soo Sunbaenim's face and I would forget all the lines. I was so nervous to act in front of someone who is my lifetime role model. I'm in the position of being her fan and I wasn't able to think straight because I'm acting with her."

Lee Jae Hoon also shared how kind Kim Hae Soo is on the film set. He shared, "Sunbaenim has an affectionate way of calling people ('Jagiya' or 'honey'). I really liked that. I learned that from her so I call all my staff members 'Jagiya'."

Lastly, Lee Jae Hoon made a request on behalf of all the 'Signal' fans. He shared, "The ending of 'Signal' was open-ended. If writer Kim Eun Hee is watching this, I want her to write the story after the end. I want her to write another story with Jo Jin Woong and Kim Hae Soo Sunbaenims. That's my personal wish."
