Hey, I recommend you the novel "The Flying of the Two Phoenixes in Time Travel". This was a Xianxia novel, and the plot revolved around the relationship between the sisters. The younger sister went on blind dates in place of the older sister, but later on, the older sister and younger sister worked hard for each other and continued to grow. In the end, they became gods and saints. I think this novel can let you feel the rich emotions and character growth from the sisterhood. I believe you will like it. I hope you like my recommendation, Mwah ~😗
