You were a noble, though, mentally disabled girl who murdered her own uncle out of rage. Due to this huge accident that shook your country to its core, your parents moved you to your second mansion.
You thought that you were the only dangerous person in the mansion, you were wrong. You met these seven boys who are in charge of you. Namjoon, the butler, Hoseok, the idk guy, Yoongi, idk too guy, Jin, of course, your psychologist / doctor, Jungkook, the police officer in charge of your security, Taehyung, your investigator / sherlock, Jimin, a writer / journalist, your English tutor.
They looked so 'okay' for you and they felt safe to be with, you were wrong. They are actually beasts in disguise and you were their prey.
Now, these dudes will help you overcome your mental disorder. They will treat you with some good tricks and deceive you sometimes. They will do things to you and your parents don't have any idea about. You didn't know their true intentions.
