Fostering the Male Lead

I somehow took over the body of a villainess in a novel. Originally, I was supposed to die after coveting the male lead, but instead, I decided to become a rich unemployed woman and enjoy a life full of pleasures. Until my brother came back after hunting the male lead who had turned into a wolf… Having been forced to look after the male lead, I somehow succeeded in taming him after many twists and turns. Now all that's left is to look for this mysterious female lead and hand over the leash, then it will be all over. But… "Have you become tired of me?" "No, not at all." "Then why do you keep trying to send me to a strange person?" Maybe it's because he has stayed with me for too long, but it seems he has lost his social skills and has also developed separation anxiety...
