The words "The Beginning of the Gold Bar" are engraved on the gold bar along with the official seal of the person who died, further strengthening the connection between the gold bar and the ghost story. The situation of Mr. Kim (Koo Min-hyuk), the security guard at the scene, was also revealed.
Kim said that while looking around the old building, he found what looked like a skeleton, and when someone came down to the basement, he threw a hammer and ran away. After Hyesung left, Kim said that he had found a skeleton in a desk drawer.
Hee-sung took out a mysterious notebook from inside the room, and found the keyword for the Byeongmoon High School ghost story written inside. Hee-sung visited the school in the middle of the night and while looking around, he found the back of the clock.
She discovers a keyhole on the side, and just as she is about to insert the key she found in the basement of the old building, Chairman Myung-ju (Kim Shin-Rock) appears and Hye-sung escapes the situation by saying that she dropped her coin.
After Hye-sung leaves the place, Myung-ju also finds a hole where the old-fashioned key can be inserted and looks at Hye-sung meaningfully.
