My Obbessed Sister

Two families lived far away from each other. The kings family and the dark one's family.
The two families had two kids each. One of each kid liked each other. The king had two daughters, Elsa and Anna and both had powers. The dark one's family had one boy and one girl, pitch black and gothel. Pitch was like his father and gothel was like her mom. Elsa and pitch met each other in a forest. Pitch was training to use his powers alone and Elsa was just taking a walk alone and somehow bumped into each other. Pitch fell on love with her and Elsa was in love with him. They became best friends and helped each other for years, until Elsa hurt her sister and she was locked away from her friend. Pitch found out about the accident and felt bad, so he visited her dreams instead. And one night his mother dies because of his father and then takes control of him at daylight. Pitch told Elsa in her dreams and she kissed him but that was the end of thier childhood until now.
