Childhood best friends Nao Mamiya and Kyousuke Miyoshi have always competed against each other, whether in academics and sports or trivial day-to-day things. Despite Nao winning every time, Kyousuke refuses to give up, hoping to defeat him in the future.

One day, however, at the age of 17, Nao is struck by a sudden illness and is hospitalized for several weeks, only to return as an "emerged" female. Much to the dismay of Kyousuke who is afraid of women, Nao easily accepts the situation and is ready to continue living life as a girl.

In a world where a gender shifting mechanism maintains a fixed male-to-female ratio, Kanojo ni Naru Hi is the tale of Nao as a boy who has switched genders, adapting to the change in his circumstances.

i found this manga quite problematic to read.

This is my first time writing a review, so I apoligize if I do a poor job.
Despite that though, I have to say this is a manga I've read the entirety of, and could never find myself enjoying.
So, what is it that makes this story so awful to me? It's the complete and flagrant disrespect and ignorance towards transgender people. (please note that I myself am not trans, but as someone of the lgbt community, this still bothers me)

Story: I'm a huge fan of shoujo, and I kept seeing this manga around, so I decided to finally read it. I'll be keeping this short, ...
