Okay so is her friend dead or alive? I’m so confused. Was she dreaming it? And what a plot twist for episode…
i believe that her friend is dead bc when the youngest sister and her friend were looking at the CCTV they saw that her mom came into the room with a coat and came out with a dress and the doll house show that she has been planning this for years now even before she mets in-joo i guess that she just needed to "cast the parts" . i think that it is also possible that they switched places because before her death she got plastic surgery .
There are different speculations about it, because it would seem that she was dreaming, but if that's true then…
i believe that Choi do-ll protected in-joo because before they left out of the car he told her to trust her cash and her gun so.. i feel like they knew that sangA was orchestrating this big reveal, that is why in-joo put bricks into the suitcase. this is just a Theory!
