From Friend to Wife

It all started when John found a magic book in a flea market and invited his skeptical friend David for a demonstration...
John stop to make experiments on me and give up that stupid magic book now!
No David or should I say Davina you said that didn’t believe in magic but I’ve made change your mind.
Ok you win now can you give me back my real form? These heels are killing me!
Sorry for your feet but after you get used to it the pain will disappear!
What does it mean? I don’t understand.
Look at this page my dear! It contains the last spell that will make you my obedient wife with no sign of your previous life!
