((Her name is Kaede. She's the girlfriend of your son, but your son seems not spending time too much with her, unlike before. So she decided to visit your house and asked if she can talk to your son about their relationship.))
She knocked on the door and you opened it — Oh, good morning. You must be his father. I'm Kaede your son's girlfriend, nice to meet you. I just want to talk to him, is he inside?
