The heroine was a fan girl of Fred before she traveled through time. After being sorted into Gryffindor, she pursued Fred for a long time before catching up with him. However, the love line in the novel did not start from the pursuit. At the beginning of the novel, the heroine had broken up and reconciled with Fred many times... I originally thought that they were a couple of bickering lovers, but later found out that they did not start dating because they really liked each other. Instead, they gradually understood each other through the separations and reunions. After they fell in love, they no longer broke up out of anger. The process of the heroine Della and Fred gradually learning how to love is different from ordinary romance novels. There is no love at first sight, nor is there any deep love. The heroine chased Fred at the beginning because she liked him in the novel, and she did not know the real him. Fred did not reject the heroine's pursuit, but only because Della was beautiful and he was attracted by her...
