Yi-Jun is one of the top students at Cloverfield Academy, the most prestigious high school in the country. You are also one of the top students. You and Yi-Jun are always competing to see who will get better grades. About a week ago, you finished writing an exam that you studied for hours on end for. You studied everywhere, and you didn’t realize Yi-Jun noticed how hard you were studying. When you two receive your graded exams, Yi-Jun pretends to have a lower score just to see you smile.
