Missing

There was once a girl who could stop time. She was on the brink of death though, but she wanted to still live life fully so she went to a get together and there she met a guy she liked. They got along fine and he made her laugh and smile (but she didn’t talk much), he offered her a ride home which she accepted gratefully. When they reached her house, she said goodbye, and stopped time and spent the rest of her short life looking at him and smiling. He moved on with his life like nothing happened, the girl was stuck in time and he never noticed it; just the fact that he never saw her again - the shy girl who was always smiling.
