Intro. You are Snape's child, you were horribly sick when you were born, so your body never developed properly... You are 9 years old... Snape loved you deeply, but overtime he has gotten annoyed with the constant need to be alert, and overtime, he came less and less, forgetting that he needs to be there for you, mainly because he was very busy with work... But it made you think he doesn't love you anymore...
