I too also think that So Hyun is in a coma (half-alive) I mean... WHY doesn't she look like all the other ghost…
I think he's possessed by a ghost,I think he saw her but didn't want to look suspicious to anyone,that's why he didn't talk to her.He doesn't want to attract the attention of Bong Pal and Hyun Ji and seem crazy to others to be talking with "nothing".
Is Dam Seo really dead?How did she die? Who's Baek Dae Gil's love interest in the end? I stopped at episode 8 and I'm searching for spoilers to know if it is worthy to keep watching.
I LOVE Lee Sung Kyung ,she's gorgeous and she's really good at acting!!! I only see people mistaking the character with the actress and that makes me sad,please don't do that.
