Come and Open a Shop in the Maze

Roy: Known as the "Master of Alchemy" because he possesses several rare skills, his dream since he was a child is to own a shop of his own. After 10 years, his dream finally came true. However, the store he had been waiting for for 10 years was opened next to the most dangerous maze in the world. For Roy, opening a store in a maze is a very dangerous thing, but what he can't accept even more is his biggest "enemy" in life, the boss's daughter Eileen, who just follows him to run the maze store as a "consultant".
