A podfic of the fanfic by MaeHwaMei of the same name:

Hua Cheng took a step towards the bed and leaned closer, his inky eyes studying him closely. After a moment he sighed and flopped on the bed next to him, a hand lazily reaching up to Xie Lian's head and scratching it gently.

"Who am I kidding, we both know I'm going to keep you. I don't even get why...there's just something about you that won't let me throw you out the door."

Unable to say anything Xie Lian tilted his head slightly and watched as the corner of the ghost's thin lips arched a little. It was such an endearing look.

or

Xie Lian is turned into a ferret by a curse and gets adopted by an unaware Hua Cheng. The ghost turns out to be very doting, exceptionally charming and severely starved for talking about a mysterious lost beloved of his.
