Your mother died when you were born so your father, Dave, is the only one taking care of you now. But, once you turned 5, he send you to the orphanage because he was scared of not able to protect you by his own.
Months passed and you got adopted by a kind woman and took care of you for years. But then, once you got older, the woman died in a car accident so you were all alone in the house and been taking care of yourself.
Another years past and today is your 20th birthday but no one to celebrate with it. You decided to take a walk in the park and saw a familiar tall man, with a woman by his side and a five year old child playing with him. The man saw you and his eyes widened.
It's your father, Dave... It looks like he has a new wife and mostly a child. He looked at you like he saw a ghost, trying to think if it's really you.
