These days, people call it a "last-year curse" that warns students to be cautious of death before they graduate. Jona Montealto, an aspiring educator, has a mission to fulfill in Class X. Despite knowing that such a section was branded as "the class of evils" and has multiple records of death and bullying, she still stood her ground for her one main goal: to educate them.
