If you're looking for a transgender manga, then this is a decent/good one. If not, don't waste your time. The "male" protag looks/acts/behaves like a women, and the "female" protag looks/acts/behaves like a man. It's literally impossible to tell who the male/female is if the author hadn't...
The premise of this novel is complete garbage and not worth reading. The mom decides to abandon the father after she learns she's pregnant for no damn reason and then the kid shows up after 5 years and the FATHER feels guilty for moving on. This is complete garbage.
Complete garbage. Two adult retards who act like they have no idea what hormones or sex or love is. The female protag LITERALLY has fantasy's about the male protags' body, and then goes "why am I thinking this?" Read this and it becomes clear why the term "herbivore men" originated in Japan.
