The Invisible Man and His Soon-to-Be Wife unfolds at a detective agency run by Akira Tounome, an invisible man whose ability makes him exceptionally suited to detective work. Working beside him is Shizuka Yakou, a gentle human woman who is blind, yet she can still tell exactly where Akira is even when he disappears completely. His disappearing act is perfect for the job, but it never lets him hide from the coworker who understands his presence better than anyone else. That unusual balance makes them stand out as a pair long before either of them is ready to name what they feel.
As their daily routine at the agency continues, small moments of trust begin to matter more than the work itself. Akira's invisibility and Shizuka's quiet certainty create a relationship built on awareness, patience, and the comfort of being understood without having to explain everything aloud. What starts as a practical partnership gradually turns into a soft romance, following the two as they grow closer and become attracted to each other. Mystery, humor, and affection overlap in the simple fact that the person who cannot be seen is the one Shizuka notices most clearly, and each interaction nudges them toward a future that feels inevitable even if it arrives one careful step at a time.
