Ok I will only say that this story and your young justice story (which I am SO happy you updated today; Not that I doubted you but it was nice getting a new chapter) have quickly become my two favorite stories on Webnovel. Looking forward to another chapter. There are few to none OC x Katara stories on any platform.
