Situation Knot

There is a 'person' in this school, a new classmate with extremely white skin, and I don't know why. Ever since new classmates arrived, classmates often disappear in the school. Teachers seem to have no memory of these disappeared classmates. Is it because of the non-existent classmate? Sheng Bei is the top student in this school. He doesn't believe that there must be a reason why all his classmates disappear for no reason. Sheng Bei planned to follow this new classmate and only then discovered his secret.
