Y/N attends Christ College, where an evil dictator devoid of creativity and happiness and who also ironically sucks it out of the pupils and teachers, runs the school; but to Y/N's shock, their seemingly aloof and stone-faced maths teacher, Mr. Griffis, has not only a soft spot for them... But also for rock ;)
