Facing the simple truth that a girl who is afraid to say it silently likes. Bright and brave, but I can't get an answer from the dragon gang. Xiunan, a serious "engineering male", turned to Chieko's sister after no hope, seeking satisfaction in Platonic "phantom". The author shows it slowly in such a beautiful way, like a trickle flowing slowly through the palm of his hand. For example, when opening the dialogue between Shinichi and Chiyoko, the author shaped the scene like this: "In spring, the soft twilight of Xishan almost dyed half the sky in Kyoto with a faint glow." Another example: Taihe Xiunan's discussion of tulips not only conforms to the character characteristics, but also vaguely reveals a very oriental philosophy. Therefore, in this beautiful, sad at the same time, slowly, let readers taste the "hope". It is a kind lie of parents to their adopted daughters, an acceptance and tolerance of their adopted daughters and sisters, a passionate love between young men and women that includes understanding others, and a tearful sisterhood that survives tenaciously under class differences. Undoubtedly, we can see the author's desire and hope for the beauty of human nature and mutual understanding between people.
