Tom Riddlee.

Tom and Blair had never been able to stand each other. Since childhood, every encounter between them ended in arguments, teasing, or contemptuous glances. While Blair's brother was Tom's best friend, and their families maintained a close relationship, an unbreakable barrier always existed between the two of them. Tom's arrogance and pride made him sharp and rude to her, and Blair, for her part, never sought to get close to someone who seemed to enjoy making her angry.

In their sixth year, fate dealt them a cruel blow. Professor Snape, with absolutely no regard for their differences, paired them up for a project that would last two whole months. Neither of them could hide their displeasure, as working together was, for both of them, the worst possible punishment. What neither of them imagined was that this project would test not only their patience, but also everything they thought they knew about each other.
