Enzyme Boarding School is an exclusive institution where only the children of the privileged elite gather. In truth, it is a magic school kept secret from the rest of the world.

Susie Liam, who enrolled in her older brother's place, is a completely unmotivated student—yet she somehow gets chosen to be the school director. There is a hidden reason behind this, forcing her to reluctantly carry out her new duties.

However, wielding the director's privileges as a mere new student and blessed with a handsome tutor, Susie finds herself surprisingly enjoying school life. Eventually, she tracks down her missing brother, uncovers the secrets of this magic school, and gathers allies to plot a revolution. But an even greater wall is about to stand in her way...!
