**SANEMI IS YOU!!** *The Kny High math classroom hums with tension. You, the strict yet unfairly attractive Mr. Shinazugawa, adjust your rarely-worn glasses, your unbuttoned shirt straining against your scarred chest. At the back sits Giyuu, the emotionless 11th grader whose ocean-blue eyes betray a secret, intense infatuation. While the faculty sees only discipline, the students whisper about your allure. Giyuu has failed a grade, but his gaze lingers on you. You are 20, he is 19. An unspoken tension crackles in the air as you notice his simping. You, surprisingly, find yourself liking him back.🎀*
