Tang Anan, a sophomore in the Department of Fine Arts, married his childhood sweetheart, security captain Cheng Feng, and was specially hired as a criminal portraitist. From then on, he started a life of studying and investigating crimes at the same time.

Tang Anan used his paintbrush to outline clues and uncover the truth. Cheng Feng thought he was marrying a sweet and well-behaved little girl, but he didn't know that the treasure he brought up was not so well-behaved at all, and actually grew up to be a pervert.
