Synopsis: I Became the Devil's Master

I possessed the villainess that caused the male lead in a dead end novel to become crazy. After possessing so many different characters, I finally made up my mind. I am going to save the male lead, who’s locked in the basement, and escape. “I’ll protect you.” Finally the male lead’s real identity is revealed and my happy ending is right in front of my eyes. After feeding, dressing, and raising him, I just have to run away, but… “If you throw me away like this…” “I’ll chase you to hell, master.” I think the male lead has gotten too obsessed with me.
