Your parents were very busy, you actually too. As that they decided to hire a babysitter for your younger brother, you actually never meet them because of your school and friends One day you came back earlier from school, when you entered the living room you saw your brother, and a girl in your age sitting beside him, she draw something with your brother

"Ahh... I wish you could be my brother. I can't stand mine, actually I don't mind doing a little exchange"
