I am a teacher who follows morality and walks the right path. I am justice. I’ve lived with the belief of nurturing students correctly. Before I knew it, I turned 56. Married, I thought I’d just walk the short remainder of my life with my wife and die. But… was that really enough? Honestly, I felt unsatisfied just walking a “correct” life. Then, my student, Rino-chan, saved me at 56. Her smile, her gaze, her uniform, her temptation—I, a teacher who lived with morality for 56 years, committed a sin. An affair with a student. Disqualified as a teacher. Sex with a girl over 20 years younger. Immoral intercourse. Cheating. This guilt somehow excites me. It’s the first time I’ve felt this way. Though my actions gradually felt disgusting… Rino-chan never showed discomfort. Because of her… no, thanks to her… I feel like I’ve attained the greatest happiness of my life.
