Every school has its own horror legends. If you hear any weird sounds here, don’t look back. This star school has produced countless elite students, but it has an extremely unreasonable senior-junior system. First-year students are forced to live as "slaves" and are always bullied by seniors who are called "kings." Alex (Ang Yunada), a freshman in high school who suffers from bullying, can only get a respite when he is with Maggie (Amanda Lorce), who is in the same year. However, one day Alex was forced by seniors to use the Pen Fairy to summon the legendary ghost, but it brought about a mysterious curse. Students died one after another, and the campus became a horrifying hell overnight.
