Sebastian Richard is a cold-hearted man. But when he sees a homeless fluffy black kitten outside his house, his seemingly stoned heart melts into a puddle. He decides to adopt her and take care of her. What he didn't expect was waking up the next morning with a naked woman beside him wearing the same collar he put on the kitten the night before. Will he ever grow to accept her and still take care of her? After all, it is said there is bad luck from seeing a black cat passing by. But then again, Sebastian is a man who doesn't believe in superstitions.
