She asked him, do you love me?
Love, natural love, I have loved and pampered her since she was a child, and want to give her the best things in the world. She is her little sister and like her daughter, because she is the only "relative". In the past ten years, he never thought that this relationship would deteriorate, and he never thought that this relationship would hurt her, because he was her "relative".
However, in their world, this love is not that love.
So she didn't want the love he gave her, and he couldn't give her the love she wanted.
