s01e12 — Episode 12

@IExposedelusion: I think they will be able to go to the second season, the rating allows

@Lanaa: first, the spirit was with the father, after the mother of Professor Em, and since both of them (with San Yong's father) wanted to get rid of him, it turns out that the spirit passed to San Yong's father, after that through the hairpin to San Yong herself.
As I understand it, Sang Yong's father went to the hairpin after the fire through an investigator (there was evidence collection and perhaps the hairpin was considered evidence, because for the 90s it was already old enough) or he found it in the ashes, because he knew the scene, judging by how he studied everything, and the woman was driving east, on the advice of the professor. That's what I understood.

At the expense of the spirit from Professor Ema's memory, it can be explained by the fact that she was getting stronger, therefore she could take on the appearance of the one in whom he was, or just memory "played" like that.
Well, at the expense of the youngest, with her too, perhaps what kind of ceremony could be done, because she is the second child, or it was a trap for the eldest.
I hope I wrote it clearly.🙈

@Lanaa: After the death of Professor Hae San's father, the spirit possessed him, it was shown at the moment where he saw his copy when he opened the door. The next moment, why did the spirit pass from Hae Sanh to someone else? There is also an answer to this in the drama, if you remember, it said that if you incorrectly call the name of an evil spirit or make a mistake with an object, then a big disaster will fall on this person, the mother, trying to get rid of the spirit, brought trouble upon herself by calling the wrong name, the same Gu Gang Mo, an evil spirit He killed them because they tried to expel him, respectively, by inhabiting them, Gu Gang Mo helped Hae Sanh's mother, because he was the only one who had some knowledge in the field of evil spirits and ghosts, but when Hae Sanh's mother failed, he decided to take the initiative hands, so the evil spirit passed to his daughter. The younger sister of the evil spirit was starved, because they believed that she was the second child, there was no mistake, the younger one died anyway, since the shaman thought it necessary to kill her, but when the evil spirit did not appear, the shaman realized that the fact was that the younger one was not the second as a child, therefore, she began to kill the eldest. And about the last question, perhaps you are right, although who knows, probably the whole village would not mind if the eldest was taken away for sacrifice, after all, at that time, it was important for people to get money and food, and who dies is not their business at all)

@Lanaa: Judging by the way the professor behaved in his childhood, Sang Yong was obsessed at that time. It's only interesting that he lived with a demon for so many years, because he died 15 years later. Apparently, all this time he was looking for answers and trying to get rid of the demon.
It's not entirely clear with his second child - what was that death for? Did she give the ghost extra powers? or did the baby die in the womb and it didn't have much effect? It was said that the demon wants to sacrifice the most precious person for the "bearer", then why is this unborn, and not a wife or daughter? Or does the second child die anyway?

Also, in the case of Sang Yong, for some reason, the process was much faster - the demon quickly and rapidly captures her in just a couple of weeks and can even control her for a long time. Well, apparently, the forces of the evil spirit grow with the increase in the number of deaths, after all, there are already 17 of them. However, it is still unclear how the professor lived more or less peacefully with the spirit for so many years.

About Hae San opening the door: when he was delirious, he saw himself standing there, with a hairy shadow. Either he imagined it out of guilt, or the demon really should have possessed him at that moment, and therefore turned out to be in the form of Hae Sanh, and the boy simply forgot it because it was too hard for the psyche, only a shadow remained in his memory.

In general, in all these stories, I always wonder how people initially learned about rituals and the correct procedures for conducting rituals (I'm talking about a shaman). In real life, it seems, well, it's just like that someone came up with and that's it, people just follow the rituals, but there is no evidence of their effectiveness.
And in such films, they clearly act according to the instructions, these instructions came from somewhere. For example, about 5 items and a name. Did the demon tell you himself in the first place? Or visions? :D

@ViktoryMartini: Ну, каким бы неприятным она ни была человеком - это не оправдывает людей, которые сделали из нее демона. Она просто была подростком и не хотела умирать, да и многие в подростковом возрасте злые и ненавидят всех - это гормоны. Если бы она не "подставила сестру", то типа всё ок было бы что ли? Нет же. Ее бы также морили городом 7 дней. Взрослые, которые принесли в жертву ребенка ради богатств и родители, которые "продали" дочь - вот кто злодеи так-то, а не девочка...

@Rai_Zap: Is the child in the basement? it was the younger sister of the demon girl, she also replaced herself with her sister, so she and her sister died in the basement, she then ran to the basement when she came to her senses to save her sister, but she was also locked there, and they both died there.
