Tuohai (Jay Chou) is an innocent young man in the original work. He is straightforward and kind, so in the eyes of Tuohai (Jay Chou), Xia Shu (Tuohai's informal girlfriend) is also a simple and kind person and a girl who really likes him. This is also the first love of Tuohai. However, when he saw the girl of his dreams with other mature men, he obviously couldn't accept the fact that Xia Shu was not as pure as he imagined, so it was inevitable to break up. After all, first love, it is normal to imagine your girlfriend as a perfect person. Of course, the cruel reality broke this perfection.

There are several points to explain about the psychology of Tuohai. Tuohai is actually a person with extremely fragile psychology. Good driving skills are only the result of his hard training. Tuohai has no maternal love since childhood and few friends, which is the main reason for his psychological immaturity. This can be seen from his loss to Keiichi Sudo that he is eager to win regardless of the burden of racing. Therefore, this kind of expansion can't see Xia Shu's true love for him, let alone understand the fact that Xia Shu left the man for him.
