I first disassembled the popular introduction of "He is actually my husband who is secretly married" and divided it into three parts: "He is actually", "My" and "My husband who is secretly married". Then, I analyzed the structural and emotional role of each part one by one, especially the shock caused by "actually" and the contradictions and conflicts contained in the "hidden husband". Finally, I summarize how these elements work together to engage readers and explain the reasons for their popularity, combined with common tropes of romance novels. This process emphasizes the core attractions of "reversal", "suspense", "secret" and "condensation".
