Alia never thought that she would meet Kia. It was true that she had asked to see her older sister, but she had never let her hopes get too high fearing she would only face disappointment later.
She knew very well what her family had done to her only sister and she also knew that Kia had refused to meet them many times.
So there was a high chance that her sister didn't want to meet her at all.
Therefore, when she saw Kia sitting in the car, smiling gently at her, she remembered her older sister who used to always be by her side when she was sick and always helped her with homework, because she kept falling behind in class because of her illness.
It was Kia who was always by her side to help her and when she was gone, it was Alia who missed her the most.
Because it could be said that it was Kia herself who had raised her.
