An otaku who loves novels, just because he said casually while reading a novel in the middle of the night, "If I were in a world of supernatural powers, I would definitely be the strongest!" Then he traveled into the novel he had just read, and traveling with him was... His own black cat?
"Good cat~I will be your father from now on"
"Meow~"
"The son takes his father's surname. My name is Luo Qin, and your name is... Luo Tan, as black as coal."
"..."
"Hi~Hello, master"
"Ahhhh! Who are you? Where am I?"
"Master, I am Luo Tan"
"You, you, you... Where is my cat? I have a Luo Tan. Don't mess around. My Luo Tan is a cute little black cat, not a handsome guy like you who has nothing to do with blackness."
"? Master, don't let me go~"
One person and one meow, oh no, a meow that turned into a human is just struggling around in this supernatural world.
Purpose: Falling in love with the master is easy
