Just my luck

The Headmaster says "Open!" Moon walks in and sees a little girl sitting at a desk, March and some woman. Moon says "Yo March, where is the headmaster at?" The little girl says "I am the headmaster." Moon says "No way the headmaster is supposed to look like some old fart, not a little girl who looks younger than my little sister." The woman says "That's enough! Let's get down to business." Moon says "So what happening!" The headmaster says "From your parents, you two will be having an arranged marriage." Moon says "Nice joke, seems like not my problem! I'll be with whoever I want to be with!" The woman says "Be quiet trash! This was what we wanted." Moon says "Well you eat it because it's not going to happen! And who are you anyway?" The woman says "I am your real mother. You both are the trash in both of the families so we thought why not let trash be with more trash." Moon says "How do you feel about this March?" March says "If both families say it's going to happen. Then I have no problems with this." Moon says "How about we make a deal mother? If I lose I will come quietly into the marriage. But if I win then you will have to do me four favors." His mother says "What are the favors and deal?" Moon says "We will play a game. The game is if make it number one in the placement test I win. If I don't I lose. My first favor is to cancel the marriage, the others you will know in time." She agreed to the deal. Moon leaves back to class.
