James Potter and Lily Evans detest each other, yet have the unfortunate situation of being forced to work together for the sake of their Headship's of the school. However, in this weird relationship, neither is particularly spiteful towards the other - they simply relish in insulting, arguing about petty things and taking part in what most call 'flirting'. Something strange is going on with the two passionate haters, and it's not their unintentional 'flirtatious' attitudes towards one another ... especially behind closed doors.
