Continuity mistake: When Weol-ju and Kang-bae are speaking in the pop-up bar near the start, whilst she says "And you also stole my ssanggapju", in an angle from behind her, her hands are not pressed together, but when it cuts to an angle in front of her, her hands are suddenly pressed together. (00:05:54)
Continuity mistake: Guibanjang picks up a cheese stick and starts to take a bite out of it. The cheese stick is at a straight angle whilst he begins to eat it, but when the shot cuts, the cheese stick is suddenly at a bent angle. His hand also raises itself between shots, being below his mouth in one shot, then level with his mouth in the next. (00:11:09)
Continuity mistake: When Guibanjang sits down at the pop-up bar whilst Weol-ju and Kang-bae are prepping food, he starts eating a cheese stick. When the camera is in front of him, it is raised to his mouth, but whenever the camera is behind him, the stick cannot be seen near his mouth. (00:11:10)
Continuity mistake: When Guibanjang asks Weol-ju "Yeo-rin's the Cinnabar", Weol-ju can be seen in the corner of shot, and there is nothing around her face. In the next shot, Weol-ju's hand is suddenly seen next to her face, trying to shush Guibanjang. (00:14:49)
Continuity mistake: When Weol-ju sits on the couch besides Guibanjang after Yeo-rin opens the bottle, Weol-ju takes out her phone. She is shown placing one finger over the camera lens on the back of the phone. In a different angle, there is no finger near the camera lens. (00:16:39)
Continuity mistake: When Weol-ju is on her phone, looking for an online post that lists the moments girls fall for guys, when the camera is on her right, she is holding the phone with both hands. When the camera is on her left, she is holding with only her left hand. (00:16:42)
Deliberate mistake: After it is revealed Won-hyung has taken over Yeom's body, he is shown walking alone on the street and says aloud "She's not afraid of going to Hell? I can't make it so easy for her. Will she be able to leave behind the person she's been pining for so easily? I can't wait to watch the heart-rending sight." There is no reason for him to say this out loud. He is alone and not talking to anyone. The only reason he is saying this is so that the audience knows his plan. (00:33:23)
Continuity mistake: Whilst Weol-ju and Guibanjang are speaking on the sidewalk, after Weol-ju says "did Kang-bae find a client? All right, let's go", Guibanjang puts his hand on Weol-ju's right arm. Guibanjang's arm is extended when he does this, but when the shot cuts, his arm is at his side. (00:34:26)
Audio problem: When Won-hyung, in Yeom's body, and Ji-hye are speaking in the department store, Ji-hye asks "What happens after she pays for her sin" whilst the camera is on her. Won-hyung starts speaking and it cuts to an angle in front of him. The first word that he speaks, the camera is still behind him and has not cut to in front of him, and his mouth doesn't move when he says this line. (00:36:04)
Continuity mistake: When Guibanjang is speaking with Samsin after looking through her stuff, just after Guibanjang says "How could you, of all people, do this", he places his hand over her hand. We can see that his hand completely covers her hand. When it cuts to a different angle, her thumb is placed on top of his hand. (00:38:15)
Audio problem: When Guibanjang is berating Samsin for not stopping Weol-ju, Samsin begins saying "I didn't want her to sign that contract either." When she begins saying the line, the camera is positioned behind her shoulder, and her mouth cannot be seen moving when she starts the line. (00:38:38)
Continuity mistake: Kang-bae enters the staff room at the supermarket and sits down in front of Yeo-rin. She is holding a walkie-talkie in an upright position, but in the next shot, the walkie-talkie is suddenly held at a tilted angle. (00:39:34)
Continuity mistake: When Ji-hye has a shot glass of soju in the pop-up bar, the glass bottle that the soju was poured from is shown on the table. The lid to the bottle can also be seen in front of the bottle. When the camera changes angles, the lid suddenly moves to the side of the bottle. (00:44:08)
Continuity mistake: When Weol-ju pours the ssanggapju into Ji-hye's shot glass, in the shot of Ji-hye pulling the shot glass toward her, we can see that her right hand is raised above her left hand. But in the next shot, we can see that both of her hands are level with one another. (00:45:55)
Continuity mistake: After Guibanjang asks Yeomradaewang to give him Weol-ju's punishment, it cuts to Weol-ju in the pop-up bar. Yeom is sitting eating with chopsticks in between his fingers, but when it cuts to a wide shot where Weol-ju says "She did, it doesn't end there", the chopsticks between Yeom's fingers are now in the bowl. They are back between his fingers two shots later. (00:54:55)
Continuity mistake: When Won-hyung, in Yeom's body, confronts Ji-hye, in the shot where Won-hyung says "Now that I look like this", he is stroking his chin with his thumb and two fingers. At the end of the shot, his thumb comes off his chin, but the gap between his thumb and chin is very small. It then cuts to an angle behind him, where the gap between his thumb and chin is much bigger. (01:00:25)
