Second, Jia Baoyu is a handsome man. In order to highlight the beauty of Jia Baoyu, Mr. Cao Xueqin used a lot of pen and ink to describe Jia Baoyu's appearance in the book. Although face value is not everything, in some cases, face value plays a key role. When Lin Daiyu saw Jia Baoyu at first sight, she was a person with fine features, which added points to Jia Baoyu's goodwill. Many women in prosperous times recognized Jia Baoyu's beauty. Under such circumstances, I think Lin Daiyu will also be tempted by Jia Baoyu's beauty.
Third, Jia Baoyu is very kind to Lin Daiyu. Jia Baoyu is a person who loves his sister and girls very much. He thinks that men are all made of mud and women are all made of water. Children who grew up in this family are generally a little domineering, but Jia Baoyu takes special care of Lin Daiyu's feelings and gives priority to whether Lin Daiyu likes it or not, as long as she likes it. Jia Baoyu is very concerned about everything about Lin Daiyu and is particularly willing to play with Lin Daiyu. Getting along is the most important thing, so I think it is hard for Lin Daiyu not to like Jia Baoyu in this process of getting along.
Although the ending of this story is not so happy, in the end, Lin Daiyu burned the manuscript and broke her infatuation, but in the first half, their feelings were still very pure and beautiful.
