The catagories this manga is listed as are about as far from the nature of the story as it could be. This is in no shape or form a romantic comedy, it is a psychological tradegy drama - the notion it could be anything else but a tragedy can only be due to either not having read the entire story or simply not paying mind to what is going on. The score will be based on MAL's listed genres.
The primary "comedy" is nothing but overused tropes - an old pervert and a massive siscon. Feeling massively out of place in the setting and artstyle, the supposedly fun scenes simply leaves you with an eyeroll instead of a chuckle.
Our protagonist (Akira) find himself unwillingly forced into the body of his love interest (Nanako) whom turns out to be one of the most egotistical and unlikeable characters you could imagine. Throughout the story it becomes more and more apparent that the supporting characters are all antagonist - his supposedly "bestfriend" since childhood attempts to rape him on multiple occasions, which for some reason just gets brushed off as "whatever". Everyone surrounding Akira shows no empathy towards his situation even as they learn it, including his family which much to Akira's distress turns out to having disliked his former self and with open arms essentially letting Nanako steal his identity. As if the rape attempts by Senbongi wasn't disturbing enough, how Nanako's best friend pays no mind to what trauma induced the dramatic change in "Nanako" cannot help but leave you to wonder if the story is about how easy it is for sociopath's to "hide" in front of their social circle.
As the story progress you can feel nothing but empathy and sadness for Akira's torment. The supporting cast slowly but surely shows to be nothing but narcissists who abuse Akira to futher their agenda. Akira is continuous exposed to physical and psychological torture from everyone which culminates in the complete and utter destruction of his self-consciousness and soul.
In regards to MAL's listed genres this is a spectacular failure that should be avoided.
If viewed as what it really is - a psychological tragedy - it is actually quite good if you can ignore the horribly misplaced "comedy".
