AU. On the second day of fifth year, Harry, not Hermione, receives a letter from Hermione's father. The envelope is marked "READ ONLY WHEN YOU'RE ALONE." For days, Hermione burns with curiosity, but Harry chooses not to show Hermione the letter. Instead, Harry sends Hermione strange looks when he thinks she is unaware, and he acts strangely. The Pink Toad gets a rude surprise.
