~A long way from sea~ (bakugou x mermaid reader)

Pet store/ Moving MY mermaid

Bakugou's POV

I don't like how shitty hair was looking at (y/n). She's my fuckin pet and I don't share what's mine. If everyone is gonna wanna get close and personal with her then I'll just have to keep her a secret. Heck even from that walking yellow caterpillar we call a teacher. I've seen the way he acts around cats and my pets the cutest thing I've ever seen so imagine what'll happen once he gets a glimpse of (y/n)! I can't let that happen. I WONT let that happen!
"Hey bakubro? Are you good bro?" I feel a hand on my shoulder and look over. I see shitty hair with a worried look on his face. "You were mumbling to yourself bakubro. We've been outside the pet store for about3 minutes and people are starting to stare. Also you kinda look like you're bout to kill someone. Penny for your thoughts?" Shark week says as he leads me into the pet store.
"Tch, I'm fine shitty hair. Just.. thinking" I said that last part more like a low growl.
"Well if you dont tell me then you're not getting that penny~" he said in a sing song voice.
"I DONT WANT YOUR FUCKING PENNY!"
"Okayy geez bakubro. Look, let's just get (y/n)'s stuff and go before you blow up the place." He sighs.
"Tch, whatever. The human size fish tanks are that way. Also you're paying for the collar. This tank, plus tank decorations, plus the filters and lights are gonna take up my two months worth of allowance. Luckily I was fuckin busy last month and couldn't use the shit." I grumble as I stomp my way over to the tank section.

"Wow I didn't even know they sold tanks this big bakugou!" Shitty hair says amazed.
"No shit, shitty hair. This is called the "giant and dangerous pet store" for a fucking reason." I reply while looking at the prices till I find one the perfect size for my dorm. "Found it. I wanna get the fuck out of here fast so go get the collar and meet me at the front. It shouldn't take long to get the other stuff. Remember, (y/n) on the front, bakugou's property on the back. Don't fuck it up." I walk away from him and continue my shopping.

Kirishima's POV

I go to the front of the store where the dog tag machine is. I put my card in and selected the shape. She's a girl so I'll get her something feminine. Girls like hearts right? Or is that too feminine? Eh, I doubt she cares much. She did agree to be bakugou's pet willingly so I doubt her standards are too high. No offense to (y/n) but I just don't understand why she wants to be a pet. And she's deathly afraid of sharks. I want to find out more about her but I don't want to get too close just incase bakugou likes her and is using this whole "pet" thing as a way of claiming what's his without being romantic about it. Not very manly but it's understandable given it's bakugou we're talking about.
"I'll just get her the bone one and call it a day. I think bakugou will like that too. I'll also get her one of those spike collars people put on their scary, big dogs." I say to myself as I make the name tag and grab the collar. I go to check out and see bakugou already there. 'Damn that was fast. Soo manly~' I think to myself.

"That'll be (I don't know yen translations to American dollars so I'm gonna use dollars instead. Sorry) $209.98. Are you using cash or credit?" The cashier asked. But then I see bakugou pull out this HUGE bundle of cash! 'What the- WHERE DID HE GET THAT MUCH?!'
"Quit staring, shitty hair and pay for the collar so we can leave."
"Oh ok bakubro" I then pay for the collar and we leave. It was only $5 dollars so I didn't have much of an issue. 'I wonder how much bakugou gets for an allowance' I sweat drop.

(Y/n)'s POV

I was playing with star when I heard a knock on the front door. 'Does bakugou not have his key?' They haven't been gone long, I think about 2 hours so they should be back within another hour. 'So who is that?' I question myself as I try my best to go deeper into the tiny ocean and hide from a possible intruder. Though my tail is too big so that might be a dead giveaway.

"Bakugou open up! Aizawa sensei wants to talk to you! He heard you had a pet fish and wanted more information on the matter!" I hear a stern and slightly deep voice say.
'Must be a guy' I think. What do I do now? The knocks on the door are getting louder and eventually he might break the door down!
"Bakugou's not here right now!" I reply to the voice outside the door.
"Wha- I um, thank you for informing me miss. Who are you exactly? I don't believe any family of bakugou came to visit today?" He asked.
"I'm, um.." I can't tell him I'm his pet given the way Kirishima acted. So I'll just make something up!
