I did not understand what the initial call was, when young suk told Sunhee to come to her house and said her mother would burn her down ... and the secret room at SEOYEON's house was also on fire,,,
and the next call youngsuk asked why SEOYEON did not come to his house, meaning the phone was received not counting down, but going forward, because the incident of being burned has happened,before of this i think the call is counting day 18 17 16 nov, but not,,,but why are youngsuk still alive? And what happens next with the secret rooms's fire(present)? Just pass without any reason

May of scene happens without any reasonable reason!



And so what the meaning of the end? I think i can understand the end not like the others comment said


Even though it was warned by her who was from present but it doesn't make sense If she can survive being pushed from the second floor because it was an accident that even she can't predict it doesn't make sense If she can prepare before, no matter what,, Moreover, there was quite a lot of blood flowing and many parts of her body that I think were broken from the position after she fall
