The "village" policeman Guan Zhi interrupted He Junyuan, who was on vacation, when he was catching fugitives and dirtied one of the latter's hot springs. After offending He Junyuan, Guan Zhi was sent to a big city, and on the first day he was drenched, he met He Junyuan. He sent him to his destination "kindly", but Guan Zhi was surprised that he was sent to become a teacher at the police academy. He Junyuan had a deep impression of this yellow-haired man who had dyed his appearance in a very bad color. When he saw Guan Zhi again, the latter had dyed his black hair and looked completely new. Guan Zhi did not know why He Junyuan came to cause so much trouble for him, but he did not know that He Junyuan was the real culprit behind his transfer to this city. After confirming what he wanted to know, He Junyuan left Guan Zhi by his side without any feelings of love, just like an interesting person. At the beginning, Guan Zhi was unwilling, but as time passed, the feeling between the two of them gradually increased. Everything seemed to be perfect, until the appearance of Guan Zhi's sister, unveiled the secret He Junyuan wanted to know the most but also the most. After learning the truth, He Junyuan did not plan to tell Guan Zhi. He could hide it from him for the rest of his life, letting him bear the burden of everything so that Guan Zhi could live without any burdens.
