I Adopted A Male Lead From A Prison Shelter

She possessed Sienna Lovett, the villain of the tragic novel. The greatest leader of the Tigers in the original novel when his Tiger Clan abandoned him for being a mutant, but that didn’t last long before the Duke came looking for his son. I’ve convinced my father to let him live with us somehow, but now I just need to succeed in protecting Ivan until the Duke comes… But when the Duke arrives, the unexpected happens. “I’ll take she too.” huh? I? Do I really want to continue living with my parents?
