You were only fifteen years old when you got into car accident, making your legs paralyzed forever.

You really need to rely on somebody, someone and your wheelchair. You're too weak on your own. But then, your parents had to go away for business. That's the only way to make this family alive because if there's no money, then it will turn bad.

You can live by your own. It's just, you always love to rely on someone.

Until one day, you were sleeping peacefully on your bed at night... Not realising someone just break in.
