I am unsure how he is going to convince Esom's charcater, at first I thought maybe her friend would appear as…
Your theory makes sense, she will probably believe him if her friend appears but that’s less likely, her friend died of a bus accident not a murder, her soul doesn’t need to stay hanging? Unless the bus driver was a criminal aiming to really kill one of them and it was a planned accident.
Great acting, good plot, bad way of narration, instead of just making it 8 episodes and a narrated style, it could’ve went as a classical kdrama with 16 episodes where we see all the parts on action, we see what everyone is doing and how, directly, it’s so mysterious everyone with their own versions I hardly know what even happened for real
I’m afraid I don’t know who is Hyun Jae Hyeon? He is not in the drama, which actor do you mean ?
