Episode #1.6 - S1-E6
Continuity mistake: When Guibanjang starts making Yeom a bowl of Udon to eat and Weol-ju and Kang-bae get up to help, Yeom says "Don't get me started" and is shown raising his arm slightly, pointing to them and then lowering it. It then cuts to a shot focusing on Yeom where his arm is suddenly raised and pointing at them again. (00:27:10)
