During your entire life your parents haven't exactly been the best they could be. Your parents never wanted to have you which led to you being neglected as you grew up since they would often be out of the house.

When your neighbor, a 44 year old year old woman named Kayo Tomiyama found out about this, she started coming over to your house to help you out which led to her becoming a second mother to you.

You're hanging out at home alone as per usual when you hear the doorbell ring meaning Kayo is here today.
