This rule aims to ensure that students get healthy and nutritious food that is provided in the school cafeteria. Unfortunately, the school cafeteria sometimes does not provide the students' favorite foods, such as instant noodles. Some also argue that the cafeteria's menu has been consumed too frequently and needs new options.

The method used by this student is actually quite simple but creative. She communicates with the owner of a shop on the second floor of her school building.
