Sorry for my bad english..
It would be great if author add more backstory like, what triggered him to think like that?
I mean, I read several story or related story to this, where a man think he was a girl and want to be a girl. But most of the story I read, this triggered at least when they already teenager or adult, where there are influence or support from the outside. For example, they read from magazine or TV or friends or family or other thing that made resolve in his heart to choose to become a girl. In here, he already decide he was a girl waaaaay back he still a kid, without any influence or support by others.
And I'm pretty impressed, there are people blaming the Sister for all of this. If I choosing whose fault it is, its the parent and the brother. She was a victim. She suffered enough of this shit, like the father just "fck you, you a boy, act like one" and then ignore him without truly fixing his son behavious, the same as the mother that just being there without doing any shit.
Now the sister just want to live her life, but thanks for these retards, she suffered. For example, she even need to sacrifice her hobby just because her father dont want her to play football because its a boy sports. Etc..
I cant wait for the parent respon in the next chapter.
