Yachi has been one of Hinata’s best friends for a long time now, so he’s pretty used to her skittish nature and random panic attacks. It still comes as a surprise when she walks into his apartment and shrieks in terror, then dives behind the kitchen counter.
“Hinata,” Yachi wheezes out through her panic, “why do you have a panther in your room?”
“Panther?” Hinata looks over to his new pet, who has padded over to Hinata is nosing his hands for treats. “I told you about him, remember? I found him on the street.”
“You said you rescued a dog!”
“Isn’t he?” Hinata says, patting Yamayama on the head.
“No! That is a full grown panther! Hinata, you don’t actually believe that’s a dog, do you?” Her voice carries a tone he’s used to hearing, although not usually from Yachi. It’s mostly a, “even you can’t be this much of an idiot” voice, and Hinata resents the tone now.
Because, okay, sure, Yamayama doesn’t really look like a dog. Hinata knows that. When he found Yamayama outside his house, injured and covered in mud, he hadn’t looked much like anything. Probably a dog. Then he followed Hinata home, and he behaved very nicely and let Hinata give him a bath and he ate half of the bento Hinata bought at the supermarket for his dinner. Yamayama was still recovering from his injuries, but he would play fetch with Hinata whenever Hinata tossed a volleyball at him, so really, even though he wasn’t exactly canine-shaped, Hinata feels like he’s justified in thinking Yamayama is just a really strange looking dog. It certainly made more sense than thinking there was a wild panther loose in Tokyo who really likes katsudon and volleyball.
Hinata tries explaining this, but Yachi doesn’t cut him any kind of slack. “He’s probably some rich guy’s pet! There are all kinds of people who keep wild cats as pets, there was a whole documentary and everything. Hinata, you have to call a zoo or something!”
“What, why? If he’s a pet, then he can just be my pet.” Considering how beat up Yamayama had been, Hinata feels like clearly his previous owners do not deserve him.
“Because he’s still a wild animal! Even the pets occasionally eat their owners.”
“Oh.” Hinata looks down at his dog (panther), who just licks his hand. Hinata pats him on the head. “Yamayama wouldn’t eat me, would you, Yamayama-kun?” He rubs the panther’s head, who starts to purr. It occurs to Hinata that he had thought the purring was strange behavior for a dog.
“Yamayama?” Yachi says, sounding surprised instead of panicked for the first time since she walked into his apartment. “Like Kageyama? Did you name your panther after the guy you have a crush on?“
The panther abruptly stops purring and stares at Hinata. Hinata jumps up and says, "I don’t have a crush on him! Shut up!”
“Yes, you do, you never shut up about him. Did you really name him after your crush?”
“‘Cuz he has black fur,” Hinata mumbles. “And he was really grumpy when I first brought him home. It reminded me of Kageyama, that’s all. It’s not because I have a crush. Because I don’t.”
“Uh huh. Call the zoo, Hinata, it’s mean to keep a wild animal in an apartment this size.”
Hinata sighs and looks down at Yamayama, who is still staring intently at him. “I’ll call tomorrow, I guess.”
He goes to bed feeling very dejected. Yamayama jumps up next to him, like he has the past couple of weeks. Hinata wraps his arms around him and says, “I’m going to miss you. I liked having a dog. You were so clean and you didn’t bark at all and, yes, I probably should have figured it out sooner, but still. You’re a good dog.” Hinata’s going to miss the company.
Hinata wakes up in the middle night to find Kageyama Tobio holding him. He’s pretty sure he’s dreaming. It wouldn’t be the first time Kageyama has appeared in his dreams. He pats Kageyama on the head, because it’s a dream and he can do anything.
“Not a dog, dumbass,” Kageyama mumbles in his sleep, holding Hinata closer.
That’s certainly a weird thing for Kageyama to say, but it’s a dream and doesn’t need to make sense. Hinata goes back to sleep.
A/N: Thanks for the prompt, friend! I couldn’t quite capture everything, but it was fun to do a different variation on Haikyuu shapeshifters =D
