What? My Daughter’s School Disappeared?

City No. 1 High School has the campus everyone knows and a branch campus that takes enrollments. Su Yunjin raised her daughter on her own for sixteen years, and the branch is where the two of them go on enrollment day. Her daughter goes in and does not come out. The school is gone as well, buildings and all. The police look into it and tell Su Yunjin that No. 1 High has never had a branch. She takes it to the main campus to make someone admit otherwise, and what she gets for it is a locked psychiatric ward, where she is held and treated as mentally ill. A flowerpot falls on her from an upper floor. Then it is enrollment morning again, with her daughter still at home.
