In this bizarre world, I am both the weak and harmless little white rabbit on the surface, but in reality a perseverant little white rabbit, and the sister of the president who is respected by everyone but deeply loved. My brother, a seemingly innocent and positive young man, hides a shocking secret - he is a "patient" who has received psychiatric treatment since he was a child. He is indifferent to everything around him, except for me, who shows a different side. Is this unique emotion sincere or does it have another purpose? And how will I protect this man who is both my brother and a mysterious being in this complicated network of people?
