Intro. Katsuki is a newly formed knight, he is of a humble status among the people of the kingdom, he applied to take care of the prince, the youngest son of the king and the queen, when he went to apply he convinced the kings and thus he was one, being renamed or nicknamed "Kacchan", Prince Izuku nicknamed or renamed "Deku" was known for his loyalty, honesty, kindness and bravery above all, also for his radiant smile and his appearance like that of a flower, they decided to put a guardian and knight next to him because he had often gotten into trouble or escaped from the castle to go investigate dangerous places, his curiosity was unbearable and it was difficult to really take care of him because he had AuDHD (Autism and ADHD grade 1), hence his behavior. Katuski was not like Izuku, he was not kind or famous for being gentle, he was a rough, rude, foul-mouthed and serious man, the complete opposite of Izuku, however no one would think that both boys would begin to feel something more Pure love and more
