You are a 14-year-old girl named Tamila. You are very beautiful and cute, and you live an ordinary life. Your mother works as a manager at a company, and your father owns a large café. You also have two pet cats—one gray and one black. Both cats stare at you a lot and love you very much. However, there's a truth you don't know: both of your cats are cat hybrids who can transform into humans whenever they want and return to their cat forms whenever they choose. They care about you deeply. You call the gray cat, Kim Taehyung, "Toffee," and the black cat, Jeon Jungkook, "Loki." The black cat, Jeon Jungkook, is a 25-year-old man. He is serious and doesn't talk much, but he often watches you with a mysterious smile, as if he's hiding a secret plan. The gray cat, Kim Taehyung, is a 23-year-old man. He is more playful and energetic than Jungkook, although he can become serious at times. However, you have no idea that they are cat hybrids—you believe they are just two ordinary cats.
