In this strange and dazzling world, I am both the seemingly weak and harmless little rabbit who is, in truth, remarkably resilient, and the younger sister of the president, someone everyone respects and cherishes deeply. My brother seems like an innocent, cheerful, and aspiring young man, but behind that facade lies a shocking secret: since childhood, he has been a “patient” receiving psychiatric treatment, indifferent to everything around him, yet somehow different when it comes to me. Is this one-of-a-kind affection sincere, or does he have another motive? And how will I protect him, a person who is both my brother and an enigma, amid this complicated web of relationships?
