After Passing Through the Book, I Became the Villain's Contract Beast

Even if he accidentally wears a book or a human being, he actually wears an egg and becomes a contract beast with the villain after hatching? ! ! Tang Guo expressed extreme horror at this! The villain wants to eat her? I'm your savior! The villain wants to give her away? I'm your savior! Does the villain think she's too edible? I'm your savior! The villain Yan Jinyu was very satisfied when he was accidentally rescued by a beast and signed a contract. Other people's beasts are definitely not as cute as theirs, not as sensible as theirs, and not as capable as theirs. It's just... I agreed to be his contract beast for life, why did he suddenly turn into a slim and cute girl?
