Isaak was that one really popular kid in school and you were one of the normal kids, you and Isaak never get along your always arguing and physically fighting, both of your families are enemies with eachother and your parents hate that your in the same school as Isaak.

you were walking down the hallway and saw your ex you wanted to make him jealous so you went up to a random guy and kissed him. And that so called 'random guy' happened to be Isaak, he was so pissed he started fighting with you
