During a break in the school day, he finds So-Young sitting on a bench near the school garden, and goes to give her candy. Hee-Min (the main character) makes plans to give a student called Han So-young candy for White Day. The story begins on the day of 13th March 2001 - the day before White Day and a day after Lee Hee-Min was transferred to Yeondu High School. 'Some sort of resurrection ritual would be incredibly dangerous, I do not want to risk it." Introduction And what if a source of Qi from the afterlife was so strong, it could do this on its own? This school has more threats than I thought. What if the wrong source of Qi from the afterlife were to go into the wrong dead body? If that were to happen, then the dead body would become possessed. I desperately wanted to investigate this further, but I had to acknowledge the risks. Let me explain: if you were to find a source of Qi (energy) somewhere in the school coming from the afterlife, and that Qi belonged to the person you're trying to resurrect, if you were to reverse the Qi emanated from the cycle of the dead person's life, you could effectively put the Qi from the afterlife back into its dead body. I found a possible way to resurrect people from the dead. ".After more days of research, I theorized about this. The possession is explained in one of the notes in the game. The master moved onto the now partially revived Seong-ah and possessed her for the next three years as an empty vessel, posing as an ordinary student. Shortly after, Na-Young attempted to resist the master of the labyrinths possession and in return, was forced to hang herself. Her mother went crazy (as was warned could happen when you try to revive the dead) and the music teacher, stricken with grief, killed himself. Seong-ah was only partially revived, with her Qi being input wrong and the master taking advantage of this to gain an empty body/vessel to possess. Otherwise, the spirits will go to the afterlife if all of them are broken. The seals also had to be broken one by one, with some seals having to remain unbroken while the land regains its strength. They successfully called Na-Young to the school at night, but somehow, the ritual went wrong because of the master of the labyrinth interfering and stopping Na-Young from being sacrificed. A person who can break the seals using the amulets (one who sees ghosts - the music teacher, Ji-won).A person who calls the dead (Seong-ah's mother, Choi Eun-mi).To revive the dead, three people were needed: One day, Seong-ah's mother Eun-mi, visited and asked for the resurrection of her daughter with Ji-won deciding to help her out so he can prove that his theory was right.
The music teacher, Ji-won, had discovered the school's past and began to study it and genuinely believed that he could resurrect the dead using the power of feng shui in the area. Seong-ah became trapped in the School because of the amulet's power and could not pass on. This upset Na-Young, and she started resisting the master of the labyrinth. Seong-ah was a very close friend of Na-Young (So-Young's older sister) and died because of her asthma. One day, in 1998, a lab fire broke out in the Home Economics Classroom, resulting in the death of Seong-ah. One spirit, the ' Master of the Labyrinth,' could not stand being unable to escape the School's hold and sought a way to escape it, eventually using the body of Na-Young in 1997, threatening that she could never leave her. This was kept a secret from that day onwards.
However, it also locked in all spirits inside the school, preventing them from going to the afterlife. He then equally spread them around the school to balance feng shui and resist the spirits, preventing them from interfering with the living. Many visitors and builders died during the construction of the building that had awakened the power (Qi) of the imbalance of feng shui and the ghosts from the hospital's past, so a geomancer was brought in to construct 5 amulets representing the 5 elements (Wu Xing). During the Korean War, the school was a Korean hospital. It is said that the area used to be a perfect natural landscape before it was built. Yeondu High School's construction led to the unbalanced feng shui around the area. It is recommended you read the Class Data notes beforehand.
