Lee Joon recently took part in an interview with TV Report to discuss his latest role as a psychopathic serial killer, Ryu Tae Oh, in tvN's 'Gabdongi.'

He said, "It was not hard to decide to play the part.  I always wanted to take on an interesting and fun role.  It came to me that a character like Ryu Tae Oh could come off simple or abundant depending on how I express and act him out . . . I did not want to do similar acting for the character.  I wanted to create an acting style unique to myself. When I practiced, I consulted the script like a textbook.  Even if it were the same scene, I practiced a variety and looked for a portrayal that I thought matched me personally."

In relation to what score he would give himself, Lee Joon said, "These days, people seem to be praising me as the best acting-dol.  I'm both grateful and burdened. There's still a lot lacking.  If 10 points is calculated as the best score for my acting, I'd give myself a 1.5.  If I were to put it in English, that would be an 'F'.  There's no scene that I personally am satisfied with.  I'm left with disappointment."

How would you grade his acting out of 10 points so far?
