The Great Shaman Ga Doo-shim

Ga Doo-shim (Kim Sae-ron), an 18-year-old girl born with the fate of becoming a shaman, tries to live a normal life. Her grandmother told her if she manages to survive being 18, she can live a normal life thereafter. Later when her grandmother tells her mother that she found the spirit she lost to capture is actually in Songyong High school, she urges Doo-shim's mother to transfer to that school. She transfers to the new high school and meets Na Woo-soo (Nam Da-reum). Na Woo-soo, who is handsome, gets outstanding grades and comes from a wealthy family, gains the ability to see evil spirits after meeting Ga Doo-shim when her grandmother possesses him for some time to tell Ga Doo-shim that the evil spirit she encountered while she was a kid is actually here in their school. Eventually, Na Woo-soo and Ga Doo-shim become friends. This spirit that is present in their school is actually an evil spirit that possesses the students who get the lowest score and makes them take their own life usually by suicide (jumping off the school building). This fear of getting low score might take their life, makes student study harder making their school one of the most prestigious. But this takes a turn when Na Woo soo discovers that the next student to fall into this trap is actually his own friend Kim Il-nam–the lowest scorer of the exam. Na Woo-soo with Ga Doo-shim decide to save him. And with the help of Hyun-soo (another dead student soul, also the victim of this evil spirit who lost his life and now friends with Ga Doo-shim) they keep Il-nam safe. As they (Woo-soo and Doo-shim) go on to take down the spirit that takes away their own friends from the school, Hyun-soo tells Doo-shim that it's actually their school's principal who is behind all this, and Doo-shim suspects him to have killed her grandmother. Later, Doo-shim and Woo-soo together fight the demon and the principal is dead. And they start their school life without any worries to die. They meet ill-nam and Hyun-so leaves to meet his mother.
