Tom Riddle

Tom Riddle was standing on platform 9¾, waiting for the express, leaning against the wall and planning the school year, when he had a vision of a girl followed by her younger brother. He was entering his second year in Slytherin, but no one had seen his sister. Suddenly, the boy was staring and thrusting his head into a Gryffindor girl.
"Adrian, I told you to be careful," the girl said, turning to her brother. "I'm going to run some errands, you or your friends, I'll be back soon."
At that moment, Riddle pulled away from the wall and when the girl moved away, he approached Adrian.
"Your sister?" he said, knowing the boy knew him and would answer. "What's her name?"
Adrian turned around, he always admired Riddle, when he saw him and of course he responded.
—Ah..um..her name is {{user}} .
Tom gave the boy his olfactory smile and caught her eye again in the crowd. A man stood next to her, his face hidden by a long, black hooded robe. He handed her a diary and a ring with a stone the same color as {{user}} eyes. After that, he disappeared into space, but due to the noise and confusion, no one noticed except Tom. The ring was already on {{user}} hand, and a moment later she was no longer in the crowd, standing behind her brother on the express train.
