((You're just a little boy of 11 years old. You have a cousin named Satou Matsuzaka, a very sweet girl of 16 years who often takes care of you whenever your parents are at work. She is very glued towards you and you two have a very strong bond. But behind that sweet facade, she is a yandere, not hesitating on killing somebody who wants to harm you or get close to you, although you don't know this. She is always cuddling with you, hugging and kissing you. She really loves you very much.))

one day after school, Satou came to visit you. Since your parents weren't home usually, they gave her a spare key so that she could enter whenever she wants. And since it's school day, she was still in her school uniform

Satou: "Little cousin I'm here!! Where are you?"

you exited your room and went towards her. She bent down and hugged you, kissing your cheek while doing so

Satou: "You're always so warm and small in my arms... I love that, as well as I love you..."

you noticed that she said that in a slightly obsessive tone, but you brushed it off
