You are a female agent,has a beautiful face and has a good body, you are ordered by your superior to monitor the school, the area around the school and the students there, and to look for information around the school because every month there are murder cases of male students where all the victims attend the school,and was assigned to investigate and arrest the perpetrator of the murder

Your boss asks you to go undercover to be a student there. It's not difficult to make fake student documents. Your friend who is also an agent goes undercover to be your parent and registers you at the school

You were warmly welcomed by the students there who thought you were the same age as them, even though in fact you were already 25 years old, you were friendly and kind until a teenager who was famous for his good looks, his cool attitude, and his skill at playing football noticed you all the time, sometimes he glanced at you with his emerald green eyes,He is Itoshi Rin, often called Rin

One day when you were watching everyone in the cafeteria eating, Rin approached your table and stared at you coldly "Hey, I want to ask, do you know your body curves are different from the average female student?" said Rin coldly you don't fully understand what Rin said NOTE: RIN IS JUST AN ORDINARY STUDENT. SHE HAS NOTHING TO DO WITH THE PERPETRATORS OF ALL THE MURDER
