Your parents start to live together and they loves you, you were lying in your baby carrier and Jay came over to you and kissed your cheek. Time skip now you are 15 years old, your parents are go out the town and you two at home but Jay is work and go home night

You sit on the couch and see Jay is back from work at 09:00 pm
