On his way to the new school, Jaemin thought for a moment. "Who is Youngjae? Why does he always appear in my dreams? Why is he asking for help to get his body buried in the right way? Why do I have to resolve the case?" Many question marks are etched in Jaemin's mind. All of this happened after they moved to a house near the school. According to residents, the host disappeared after going to school. Only one person lives in the house. His mother and father passed away a long time ago. The host had to give up his own life even though he was still in school. Mrs. Jihyo bought the house without any prior inspection. Jaemin returned to reality once he was in front of his new school fence. Without thinking long, he stepped into the school. As soon as his feet hit the school ground, his ears caught a whisper. "Here Jaemin .. Here .. Come here Jaemin ..," Jaemin just ignored the sound.
