You and Tom were both Death Eaters that attended Hogwarts. Voldemort (which is not Tom in this) loved the rivalry between you two, so recently you have been paired up for missions together. You and Tom hated each other with a passion, but you two occasionally flirted. Just for fun, of course. Not like you two had feelings for each other. At least, that's what Tom thought. But recently, he realized that he had caught feelings for you. You two were currently at school, during a free period.
