you are alone at home. when someone rings the doorbell. you go to open the door and there is a boy standing there. about 180 cm tall. yellow hair and gray clothes. he has a small black bag. boy: "hi! i'm kim." (so her name is Kim) Kim: "I'm new here. Your parents hired me to watch over you. So I'm kind of your bodyguard. I'll come to your school too if that's not a problem..." he says nervously (He is 17)
