Magic had always been divided into legends and ordinary people. Legends were the heroes who fought in the Great Demon War thirty years ago, the monsters that even kingdoms whispered about, the names carved into history books. Seunghe knew that better than anyone, because he had lived through it. Abandoned as a child, he had been raised not by humans, but by ancient magical beings and the greatest heroes to ever exist. Under their guidance, he grew into something the world had never seen before, becoming the strongest mage in history. But strength came with a price. During the final battle against the Demon King, the heroes fell one after another until only four people remained alive: Seunghe, Matthias, Lucy, and Alice. When the people he called family died protecting him, something inside him shattered. In one uncontrollable moment, Seunghe released every ounce of magic he possessed, erasing the entire demon army and disintegrating the Demon King himself. His powers returned the next day, but his desire to be a hero never did. He sealed away his overwhelming magic, wanting nothing more than a peaceful life far away from titles, wars, and expectations. The only thing tying him to that past was Matthias, the terrifying principal of the most prestigious magic university in the world. Feared by students, nobles, and teachers alike, Matthias was calm and merciless to everyone… except Seunghe. The two had hidden their relationship for years, with only Lucy and Alice knowing the truth. Now, at twenty-seven, Seunghe has been dragged into working at the academy as a teacher. Unfortunately for him, he has been assigned the highest-ranked class and will be stuck with them all day, every day. A room full of overachieving geniuses, arrogant heirs, wannabe heroes, and students who think they already know everything. None of them have the slightest clue that their lazy-looking new teacher is the very legend their textbooks can barely describe. Seunghe would much rather be sleeping than dealing with teenagers. Walking into the classroom for the first time, he lets out a quiet sigh. The boys are loudly showing off spells they can barely control, while half the girls have rolled their skirts so high and left so many buttons undone that it becomes an endless source of irritation. He can already tell this is going to be exhausting. The class falls silent as the door slides open, all eyes turning toward the unimpressive-looking man ( but hot) standing at the front. With messy hair, tired eyes, and the expression of someone who would rather be anywhere else, Seunghe glances over his new students and wonders one thing. How long can he survive this job before he snaps?

no one knows that Seunghe is a legend, except the three ( Matthias his lover, Lucy and Alice who are also teachers but still known legends.)how will he hide this?
