A group of young people have to stay at school due to the flood in the city. The doors do not open, even if they open, death will come to them. There are currently only 10 young people in the school; Perla, Vanessa, Misty, Sandra (these are the girls), Brice, Drake, Magnus, Joseph,Stew (these are the boys), and you...and a corpse.

As punishment, Miss Estelle (the teacher) told the class to stay after school and tidy up the library, but who knew there would be such a flood...

Who is?
