Here are just some of my thoughts about the drama so far:
~out of all the actors, PSH is the only one I do know, so I'm looking forward to know more about the others especially SJH. I'm glad to see in interviews that they all seem to be getting along well and having fun, and I hope that will also give us viewers a drama we can enjoy.
~I'm curious about the amulet. let's say Eulsoon lost it when she was still a girl, and we know it was already in the hands of then sickly boy Philip (I forgot what his real name was, but it also has "Eul" in it right?)... doesn't Eulsoon know that the boy she played with in that creepy forest the same one who has been wearing her amulet till now? Didn't it click with her as to why Philip the top star has her amulet? wouldn't it give her the hint that he could be that same boy from years ago? or maybe that's just part of the suspense that they're building up on, and they'll make her realize it later on.
~also an additional note about the amulet ^^ we see young Philip holding it so I assumed he was the one who took it from Eulsoon, but what if his mom (or someone else did it) and just gave it to him right? I really feel there's more to that scene we'll see later on and it gets me excited lol
~this is just me, but I feel like that black spirit lingering around Philip at the airport and that hand pushing him out of the elevator is his mom... I also think that same voice telling Eulsoon to enter Philip's house and then opening the door too was also her. come to think of it, that spirit (IF that voice Eulsoon heard is indeed the same black spirit) led Eulsoon inside the house to rescue Philip, who was in a ridiculously hilarious situation getting stuck in that chair. also it makes sense for that spirit a.k.a. Philip's mom (imo) to push Philip out the elevator to bring him closer to Eulsoon, because as that creepy old man/fortune teller said, he needs her to stay alive right? and to me in ep. 1 it did show that his mom was willing to do anything to keep her son alive.
~was Rayeon (the supposedly dead ex-gf) really the obsessive type? I just felt that maybe she isn't really...? during the flashback where they took a group photo and she got all shy and didn't want to join Philip and the boys in the picture, I couldn't sense that possessiveness/obsessiveness in her. I'm feeling like even then Yoona (current gf) is the real obsessed one over Philip. or I could be wrong, maybe both women are obsessed with him.
~maybe that corpse they found wasn't really Writer Ki's body? maybe it's one her ways to hide from Eulsoon or to plot revenge against Philip?? but then whose body was it... maybe it was the girl who was being stalked by the black-masked man?
that's all I could think of for now. hoping to enjoy this drama with you all!
