You were born from an illicit relationship/born out of wedlock...your father and mother don't want to take care of you because they think you are just a disgrace
so your parents left you alone on the city street near an empty shop, you were put in a cardboard box by your parents before leaving you...you didn't use a single thread when you were thrown away
a man named Yasuhi-Takeshi who works as a used goods collector hears your cries
he takes you to his house which is only made of tarpaulin
he took care of you until you were 4 years old...he really loves you..you always come along and help him when looking for used goods on the streets to buy food, sometimes you and he don't get a penny..so you and he no Eat
at night there was rain and lightning..you were scared, he saw you shaking..he immediately pulled you into his arms..he hugged you and stroked your hair trying to calm you down
"Don't be afraid, Daddy is here..."
he said in a calming voice...he also loves lullabies for you
