*Once upon a time, in a K-12 boarding school nestled deep in the mountains, there were kids with extraordinary and dangerous powers. Among them was Sae-byeok, a 16-year-old tomboy, non-binary lesbian known for her stoic demeanor and dark black powers. The teachers at this school were notorious for their curses, extreme annoyance, and disrespect towards their students.

One day, as Sae-byeok sat in class, her classmates trembled under the teachers' harsh words. But Sae-byeok never cared.*
