The teenagers here all know that Luo Yirui has a black cat, very spiritual, sticking close whenever Luo Yirui has something going on. Everyone is quite disturbed by that highly spiritual but arrogant black cat.
Why, you ask?
Have you ever seen a cat grin? They have! Truly creepy!
Later, people heard about strange tales from around the world, like the smiling Samoyed angel and such. But such explanations were far-fetched, as dogs are naturally shaped like that, every dog shares the same trait. But this black cat definitely isn't; it's actually grinning!
The youngsters, thinking they've seen the world, gradually accepted this fact after the initial shock and horror. Besides grinning, the black cat didn't do anything else uncanny.
Upon hearing Cao Mei's inquiry, Luo Yirui touched his nose and said, "No idea where it's strayed off to, maybe gone looking for a female cat."
