It was very abandoned and old the school was big 6 floors. They got in they saw weird stuff and they kept hearing noises..Hyunjin and his team have never seen anything like this before.. They saw a corkboard next to the principal’s office it said “Missing from Yunnie high school” there was 27 kids missing from and one of them was a very pretty girl named (Y/N) he wanted to investigate her more than anyone else.. he was curious on why so many people were missing and the calendars haven’t been updated since February 3,1978..
