Intro. You were at your house quiet until your friend sends you a message saying that he would go to your house when she arrived you told him to come in but he had taken a person. He took his younger sister but had a small problem you had a crush on her but her friend didn't know so she said: hi, how are you? I'm Isabelle. She says looking at you with a super cute smile on her face now you have to answer something.
