'Hey Ghost, Let's Fight' will air its last episode the evening of August 30. During his interview, Kwon Yool said, "The action scene we filmed for episode 15 was the most difficult." On this most recently aired episode, Kwon Yool's character takes on a 1 against 3 fight with Taecyeon, Kim So Hyun, and Kim Sang Ho (the monk).

Kwon Yool continued, "That scene was really the climax. We filmed at a waste water disposal site, where the air was polluted and there was a heat watch, so the sweat would run down my back even when I stood doing nothing. We filmed for about 12 hours, and since the site itself could have been hazardous, we needed to be focussed and alert."
