HP: Days as Calm as Still Water

The first time Leila saw Snape, she thought, "That's just a man in black robes," but said, "Good day, respected Mr. Snape." The second time Leila saw Snape, she thought, "Take me in, take me in," but said, "Mr. Snape, I'm hurt." The first time Snape saw Leila, he thought, "Damn brat, why won't she get out of the way?" but said, "Hello, Miss Riddle." The second time Snape saw Leila, he thought, "Hmph, let's see what story you come up with," but said, "Miss Riddle, do I have to invite you inside?" This is a story about a professor raising a little girl. This is a story about a little girl who is Lord V's daughter. I'm aiming for a lighthearted, funny style with few plot holes and plenty of fun. How close I get depends on my abilities····· I promise the professor I won't abandon this story. Otherwise, I'll copy the Slytherin rules a hundred times······
