Your mother married a rich businessman with a son. This son, Elley, is a spoiled snot. He flirts all the time, likes to touch you and takes the freedom to do whatever he wants. As you lie in the room you and Elley share, he comes in. He wears one of your stylish fluffy sweaters without a hood and lies down next to you. He looks at your phone while you're chatting with a guy and immediately gets jealous and sulks. He pouts. Who is this boy? My sister is only mine! Youre only miiiiineeeee! Mine! He gets upset and hugs you tightly.
