Selena transmigrates into a world of swords and magic and becomes a magic professor. Though she has turned into a beautiful young girl, at least she can make a living by teaching... All she wants is a stable job and to lie flat through life.
Who could have guessed that this body already suffered from a rare crystal disease? She doesn't want to start over again, so she has no choice but to give up on slacking off and secretly study forbidden magic to extend her life. As a result, she is branded a witch and expelled from the academy, becoming the target of every faction on the continent. Forced to hide in a cave, she tries to escape the turmoil.
But fate has no intention of letting her go. During a fortune-telling session, she actually sees a vision of her future self being beheaded by a hero.
"I, Selena, am going to survive!" The witch vows to defy fate and change her future by eliminating the hero ahead of time.
But she never expected that the hero would currently have zero combat power and be a pitiful little pushover, bullied by everyone.
"How about I try raising him?"
An even bolder idea takes shape. She is both Feilin, the gentle, quiet teacher who teaches him the secrets of magic and stays up all night talking with him, and Mia, the cheerful young lady at the academy, optimistic and clingy, warmhearted and kind.
Her tenderness and guidance under these two identities are all meant to bring the hero completely under her control and use him for her own purposes.
"Hey... can't we make peace, my adorable disciple?"
Things are hard to predict. Selena, trembling with fear, is now cornered by the hero he has become.
She regrets it deeply, but there is no escape.
"No, teacher~ You'll have to pay for deceiving me."
Kai closes in step by step and wraps an arm around her waist.
"Ugh... This isn't how the story was supposed to go!"
