Starting a new school how do you make sure that all the boys fall in love with you?

There is no person who "everyone" falls in love with - you will be lucky if you find one person who truly falls in love with you. The only way to really find love is to be yourself and not try to "make" anyone fall in love. Also, you seem to be missing the point of school, which is to learn skills that will help you survive and succeed on your own, not to attract boys.
