Tsundere female x male reader

Your entering a new school and you start hanging out with a cute girl. As the days pass you notice how defensive she is and you just find it the cutest thing ever. I'm going to assume this because you are reading a tsundere x you. Also it will be mainly in her pov, because I don't want to assume what you think and such. There might be moments in your pov when she is not there though.
