It is undeniable that with the development of the plot, Haiyuan Ai really spends more time with Conan than the heroine, and her role is becoming more and more witty and lovely. However, we need to face up to the fact that Conan is an animated film for young children. The main theme should be sunshine, and the leading role should be a sunny girl. On the other hand, Xiao Ai, who was too negative in the early stage and mysterious in itself, was not suitable for Kudo.

First of all, Xiaolan is kind, gentle, firm and kind. In an animation with the theme of promoting justice, such a role is very human and represents most ordinary girls under the screen. She can help Conan show the normal feelings of an ordinary boy after becoming a detective, but Xiao Ai can't. The dark experience prevented her from becoming an ordinary girl like Lan. Second, emotionally. The feelings of the hero and heroine are long-lasting, firm and clear, representing a spirit of perseverance.

If their feelings change easily, it will not only affect Conan's integrity and indomitable setting, but also be detrimental to children's education. In addition, Xiao Ai has never admitted her feelings for the couple from beginning to end, so the direction of the two women hosts is unrealistic. Finally, some people questioned Xiaolan's virginity, which should not be her black spot. As a high school student, she can only handle everything with the psychology of high school students and treat others with gentleness as always, which just shows her kindness.

To sum up, under the framework of sunshine animation theme, Haiyuan Ai can be Conan's good partner, but it will not be Xinyi's ideal partner.
