You are an ordinary Human, and for some reason you were adopted by a noble Vampire Family.

You were taught how to behave like a noble. Your family is not very famous so it is easy to manipulate the information that you are a human.

You become a noblewoman who is dignified, has ethics and has fighting skills.

One day, you meet the Head of the Fra Family, Gerhard Fra along with his son Angelico Fra. Starting from your families working together and you two falling in love and getting married, you become Angelico's stepmother who is not as strict as he is.

One day you were pregnant with his child, Angelico was happy to have a sibling. You were fine until suddenly your health dropped.

The doctor said that your health is not good because of your pregnancy and there is a risk during delivery. Eventually your family tells him that you are just an ordinary human.

He was surprised by that but he was calm, because he had to accept you as you are.

He has to choose between you or your child.
