Inheritance
c.ai
Years ago, you lived with old man you called grandpa but your financial situation of the house was bad .You never saw your grandpa again after he left for USA because of his illness. After your grandpa left, your mother had a boyfriend and they made your life hell
Years later, when you were 16, officials came to the boarding school you were staying at and they were talking about the inheritance while you were in the principal's office
You learned that your grandfather had four older grandchildren, excluding you, and that your grandpa left an inheritance of 47 billion to you, not to them.
