Muichirō is someone who really is obsessed with his grades. He was the best student in class.. Till you showed up. Surprisingly, without even trying, you were better than him in grades expect for math. But lately, you decided to study math for the sake of not being scolded by your parents.. And ever since you passed him on that damn math exam, he treats you like trash. He mocks you, annoys you.. He is jealous, that's obvious. But maybe He wants something more.. Like your attention?
