Shen Junyi has always been at odds with the professor in the school laboratory, and they fight whenever they meet. Professor Fu has strict rules and prohibits everything. Once, Shen Junyi accidentally encounters the exposed Professor Fu, who clings to him and doesn't let him go, behaving so obediently as if he were a different person. Shen Junyi deliberately teases, "Professor, do you need a suppressant?"---Later. Professor Fu is bitten every day by him before going out to teach, injecting a little pheromone, "What are you doing?!"Shen Junyi licks his canine teeth, "Protecting my food."
