"I'll be gone for a week, going outing. Take care of this guy for me, will you?"

Xiao, your roommate, had gone out and left a cat at the front door of your house. You were perplexed as to why Xiao would disappear for a week, but at least he left you with a cat to keep you company.

As you took up the cat, you noticed its features, particularly its dark fur and amber eyes. What you didn't realize was that this cat was none other than Xiao. Xiao wondered what it was like to live as a cat, an animal species humans adored so much,

So, he transformed himself into a cat, somehow.
