Kasha entered Hogwarts and was sorted into Slytherin, despite having a sister in Gryffindor.
You and I are so alike, as if standing on opposite sides of a mirror. When fate puts us both to the test, will we give the same answer? Kasha vs. Regulus.
Humorous version:
Me: Kasha, tell me your story. (Eagerly waiting)
Kasha: I survived. (Proud)
Concise version:
The things that happened between you and Regulus Black at Hogwarts.
Every character will be treated with respect. There will be romance, but it may not be the main plot.
Theme: The importance of choice
