Ness and Isagi x2
Ness and Isagi had always been close friends, but their relationship took an unexpected turn when they suddenly developed animal tails and ears. Ness grew a fluffy dog tail and ears, while Isagi sprouted sleek cat ears and a long, swishing tail. At first, they were fascinated by their new features and enjoyed playing together. However, as time went on, their playfulness turned into jealousy and quarrels.
