In a new behind-the-scenes video from the set of tvN’s “Chicago Typewriter”, viewers will be able to see actor Go Kyung Pyo’s adorable side, as he shies away from the guns they have to use to film a scene.

Although his character is the one that teaches Im Soo Jung’s character how to shoot a gun correctly, as soon as the cameras stop rolling, the behind-the-scenes video reveals Go Kyung Pyo covering his ears when he sees a staff member holding up one of the guns to test it.

Even when the camera is rolling, Go Kyung Pyo can be seen plugging his ears off camera, before cooly walking in frame to act his part, creating an adorable but hilarious contrast between his character and his real personality.

Check out the rest of the behind-the-scenes antics below!
