Beatty, a weak squirrel shapeshifter who was born into a lion family. Because of that, I lived my life being ab*sed at my aunt’s house in the Capital. When I told my only friend and fiancé, the Second Prince, that I would leave to achieve my dream, ‘Ritter, you bastard…!’ I died on his fangs.

When did you grow up like this…?” “Young Miss is walking with those two cute feet!” … Huh? Why am I welcomed like this? No way, is that my statue?
