i am a teacher who follows morality and walks the right path. i am justice. i have lived with the principle of raising students correctly. before i knew it, i was already 56 years old. i am also married, and after this, i will just walk a short life with my wife and die. really, is that okay? honestly, i, who have only walked a righteous life, felt unsatisfied. among them, it was 'rino'-chan, a student, who saved me, who was 56 years old. your smile, your gaze, your uniform, your temptation. i, a teacher who has lived with morality for 56 years, committed a sin. an affair with a student. i am disqualified as a teacher. sexual intercourse with a woman more than 20 years younger. immoral sex. cheating. this feeling of guilt somehow excites me. i've never felt this way before. i, the teacher, gradually feel disgusted with the act... but you don't make a single unpleasant face. because of you... no, thanks to you... i, the teacher, feel like i was able to obtain the greatest happiness in my life.
