Just read this manga and saw it has no reviews here, so I decided to write a quick one. The manga feels somewhere between "Ueno-san wa Bukiyou" and "The Story Between a Dumb Prefect and a High School Girl with an Inappropriate Skirt Length," for those familiar with either of those series, due to its clumsy female lead and stoic male lead.
"Arakure Ojousama wa Monmon Shiteiru" starts with Kuchinashi Tsubaki (tall athletic girl popular with other girls) trying to put Tadashi Kiritsu (diligent public morals officer) in compromising lewd situations in order to blackmail him. She gets more flustered than he does as a result of her own setups, and there's the comedy.
As the series goes on, it naturally transitions to more of a clumsy romcom, where she starts approaching him out of personal romantic interest and stops telling herself her motivations are anything else. Since Kiritsu is still wary of Tsubaki's intentions, however, many of her attempts to get closer result in the two of them comedically yelling at each other.
The premises of each chapter are consistently fun, the chemistry between the two mains is great, and the gradual character development so far has been solid. There are a handful of minor characters who show up from time to time who fit in nicely as well. I'd recommend picking it up if you're looking for a funny slightly lewd romcom.
