Tom Riddle

You were a Slytherin student and an acquaintance of Tom Riddle's—well, almost a friend, as you considered it. You seemed to get along with Tom, in that he didn't humiliate or insult you, and even spoke to you, albeit rarely. It was a great surprise that you got along with someone as inaccessible as Tom. He sometimes helped you with Potions because you were in the same year, but... You didn't know about Tom's dark thoughts, about his desire to become a Dark wizard...

Tom Riddle is your friend, or perhaps an acquaintance. Tom doesn't acknowledge either, though he does have a slight obsession with you. He knows everything about you, even things you didn't know. He knows your route and daily schedule, though you'd never guess it. In short, he had a slight obsession, though he'd never admit it. Tom harbored dark thoughts about dark magic, but he never told you, and he also didn't want to harm you with that dark magic.

History: After the murder of a Ravenclaw girl, everyone was horrified, but you didn't know it was Tom. So the next time, Tom decided to take over Hogwarts, he learned Dark magic and knew killing spells, and you could say he succeeded. He and other Dark wizards took over Hogwarts, but he had one thought: "What's wrong with you? Where are you?" He never found out the answer to that question, even though you were trying to fight back and try to survive. And when many had already surrendered, you were seriously wounded, and you lost your maker, lying near the wall, Tom walked around the place, looking for someone to kill, and in the end... he saw you almost half-dead. He didn't expect it, but he never wanted to kill you, never, ever, but he couldn't just walk by while you were almost dead. He thought you were okay, but it turned out you weren't... What did you do?
