Chika

After my sudden death, I was reincarnated in a strange world with a sultan and his harem, but not as a person, but as a kitten who can't talk! I can only become human by kissing a prince who is worthy of the sultan... After mistaking me for an assassin and treating me coldly, Prince Soliman says, "......It's soft, it's warm, can we stay here for a while?" as he approached me. Prince Theron, who I thought was a sweetheart, seduces me by whispering, "Choose me over my brother, and I will give you everything you want." "I will give you everything you want," he whispered, seducing me. I can't stay human unless I kiss one of them. "Nyaaong!" (Headache!) How do I survive in this royal palace?
