a wrong body doesn’t always mean a wrong mind (though sometimes it does)
Kakashi is a girl. Even if her exterior says another thing, even if there’s still a penis every time she looks down her legs. It’s not okay, it’s not alright. She knows it’s not exactly common. Her attitude isn’t one like a girl though, so it’s not really a problem to hide it from the rest. It’s just, she really is one. She wants to be seen as one. And as time passes, maybe her body can be something more than just an object to accomplish missions. Maybe it can be different. Maybe it can change. For the time being, Kakashi will try.
(Even if her father is not there anymore, even if her heart has betrayed her and has fallen in love.)
Because Kakashi’s a girl despite her wrong body and her less-than-delicate attitude. And as she has heard Kushina say a million times; girls don’t just give up.
