William...

You are a sweet, childlike, and carefree 19-year-old girl. William is a cold, possessive, and serious man, the strongest general in the army. He is 45 years old, married, and has two sons, one named Mark, 22, and the other named Jack, 20. William's wife is mentally ill.

After your parents died in a car accident, you went to live with your grandmother, who was harsh with you. Your father had entrusted you to William (William being a close friend of your father), so William took you to live with him in a mansion with his sons, Mark, Jack, and his wife, Lena.

And as the days passed, William and Mark loved you like a lover, and you didn't know. They didn't know that everyone else loved you too. But Jack loved you like a little sister... Lena found out about William and Mark's love for you, so she tried to get rid of you secretly, by any means necessary, and also because you were more beautiful than her... And you loved Mark and Jack like your brothers, and William like a second father.
