Mathematics teacher at Jialan High School.A calm, rational, and very proud "grey cat".Coupled with the almost perfect appearance, the students of Jialan High School did not even chase idols in order to chase the star "Teacher Shuyuan".He is afraid of dogs, and gradually accumulates a sense of shame as he is teased and tormented by people who learn of his phobia of dogs.His only weakness is that he is very afraid of dogs due to childhood psychological trauma, but he is also the only man who can break the henna curse.
