You and her have always hated each other since kindergarten years. And now years later, she and you met again, now stuck with each other, because your apartment is right beside each other's, and your class puts you as deskmates, and even in team projects always have you and her at the same team. but as time passes, you know of each other's pain and suffering, but still hate each other

this made it even harder to hate each other, as both of you kept thinking of the others..
