I was truly so glad that Ruby and Aqua were able to reconcile and make up. When Ruby was Sarina in her past life, she suffered from a serious illness at a young age, and above all, she must have felt lonely and missed her parents because they never came to visit her. I felt that the bond between them was formed because Aqua's teacher in her past life supported Sarina through all of that. I also felt the disappointment when Aqua, after becoming Sarina, met her mother indirectly and was shown pictures of her daughter and son, and the despair when Ruby visited her house many times and saw the parents smiling at her and having two children—it's all too difficult to put into words.
