During the show, Yoo Yeon Seok was asked whether he had ever been jealous of his “A Werewolf Boy” co-star Song Joong Ki. Song Joong Ki played the male lead in the film while Yoo Yeon Seok played the antagonist.
To the question, Yoo Yeon Seok answered playfully, “About 5,000 audience members attended a screening event with myself and the other actors. After watching the movie, the audience clapped a lot. Song Joong Ki and Park Bo Young waved to the crowd so I followed suit, but the crowd pointed and booed at me.”
