'Goblin' actors Lee Dong Wook and Yoo In Na showed off a friendly chemistry in a making film. 

On December 14, tvN released a behind-the-scene clip of the actors shooting a scene of the two characters meeting for the first time. In the video clip, Lee Dong Wook and Yoo In Na can be seen playing around and joking while rehearsing the scene. 

They are shooting 'bullets of love' to each other and pretending to die by the bullet while laughing happily. Lee Dong Wook can be heard saying, "If you do that, you're seducing me." 

Watch the happy couple in the video above!
