Magician of HP Clow card

Summary: Molly, who was alone at home with cp Severus Snape, unfortunately traveled through time while cleaning the underground study. She was orphaned and without a golden finger, so she was adopted by the kind-hearted Bude family. She thought she would take the route of a genius girl. But at the age of 11, he became a Clow card magician. Then an owl came quietly... The author's favorite CP: Grindelwald x Dumbledore. So there may be some BL plot. Please row away if it's thunderous.
