Content: Polyam relationship, mutual pining

Warnings: If you don't like poly, then leave me alone. Don't comment anything negative on it, please.

Notes: I'd so be in a polyam relationship with these two. I'm also kinda iffy on how this came out, but oh well. It's my first time writing polyam, so for my first time writing polyam I think it's good! Also please note that I haven't seen MHA/BNHA in a long time. This is just how I remember these guys.

(Y/n) watched the two boys playfully argue over something in the study hall. Sitting almost shoulder to shoulder, (Y/n) felt envy and sorrow bubble up in their chest. Both boys captured their heart and held it hostage, but anyone could see plain as day, that the two boys were a couple and weren't interested in them.

Sighing to themselves, they set their stuff down at a table some ways away from the two. Both were so loud that no matter where they went, they were always within earshot. Taking out their book to try and study, slowly the boys' commotion was being drowned out by their own thoughts.

The words on the pages, at first, were comprehensively taken in, but soon they began to blur as their mind wandered. Wandered to how dating each boy would be. How good of a kisser each boy would be. How each boy would hold them at night, how each boy...

"Oh, hey (Y/n)!" Izuku broke them out of their thoughts. "Mind if I sit with you?"

(Y/n) blinked themselves back to reality and looked up. "Huh? Oh, sure."

Izuku sat himself across from them. "I don't know how you've managed to study, what with Kacchan's and Kirishima's yelling..."

"Oh, studying, yeah..." (Y/n) looked down at their book.

Izuku was silent for a moment before chuckling. "You weren't, were you?"

"Ah!" (Y/n) snapped their gaze up. "I was! I just..."

They glanced over their shoulder at the boys, who had gotten suspiciously quiet all of a sudden. "Got a little carried away..."

Izuku laughed. "Sure you did! Hey, I can help you, if you'd like?"

"Uh, yeah, sure." (Y/n) went to spin their book around to let Izuku see, but a third, firm hand planted on it.

"That wont be needed, Deku." Bakugou growled.

"O-Oh! Kacchan...!"

Bakugou growled, but (Y/n) stepped in before a fight could break out. "Bakugou, what is it?"

"Just came to see if you needed help." Bakugou's tone softened when he turned to them.

"Ah, Izuku already offered-"

"Well now I'm offering!" Bakugou yelled, getting glares from other students around the three.

"Alright, alright, if it'll make you quiet down then fine..." (Y/n) gave Izuku an apologetic look.

Bakugou huffed, then sat down next to (Y/n) and glared at Izuku. "Scram, Deku."

"Sorry, Izuku..." (Y/n) mumbled.

"Ah, it's okay! Call me later, alright?" Izuku didn't seem too bothered.

(Y/n) nodded with a smile, watching their friend walk away. They then turned to Bakugou, who was sitting close to them. Their face grew heated, and they turned their gaze to the table. "R-right...let's just get this over with..."

~*~*~*

After a few hours, the pair had decided to stop their studying for the day. They left the school together, side by side and pretty much shoulder to shoulder. Bakugou finished the punchline of a joke to which (Y/n) laughed at. Bakugou let a smirk take over his lips, his crimson gaze lingering on their form.

Once their laughter died down, Bakugou glanced over at the sky. "Ah, hey, it's the golden hour."

"Woah, we stayed really late. Will Kirishima be upset that you spent so much one-on-one time with me?"

Bakugou grunted. "I dunno. You tell me."

"What? But...but aren't you two...dating?" (Y/n) looked at Bakugou in confusion.

Bakugou's gaze snapped to them. "Huh? No! I thought you and shitty hair were a thing! Don't think I haven't noticed how close you two have gotten, giggling and whispering in class and shit."

"Wha- but- so...so you're not dating him?"

"No! I thought you were dating him!" Bakugou yelled in frustration.

"No, but I wish!" (Y/n) yelled back.

Bakugou stopped and stared at them. He looked hurt. (Y/n) then spoke again.

"But I...I also want to date you."

"You...you want to date both of us?" Bakugou spoke with a rare soft tone. "As in...like...a polyamorous relationship?"

(Y/n) nods. "I guess something like that, yeah. O-only if you'll have me."

"Of course I would! Are you fucking kidding me?! I've liked you for a while!" Bakugou went back to yelling.

Both of them looked at each other for a moment before (Y/n) spoke up. "...I need to talk to Kiri."

"I'm coming with."

~*~*~*

(Y/n) knocked on Kirishima's door frantically, Bakugou standing really close behind them. It didn't take long for the red head to open the door.

"Oh, hey (Y/n)! Bakubro, you're here too? What's up guy-"

"Cut the shit, Kiri." Bakugou leaned over (Y/n) and rested his arm on the door frame. "Are you dating anyone?"

"Ah, no. Why?"

"Good. We need to talk to you." Bakugou pushed past (Y/n) and Kirishima and walked into his house.

Kirishima and (Y/n) shared a glance before the red head let them in. "So...what's this about?"

"We wanna date you." Bakugou spoke bluntly, crossing his arms.

"Ah-! Katsuki! I was gonna ease him into it!" (Y/n) fumbled at the spiky ash blonde.

"Well you shoulda beat me to it!" Bakugou yelled at them.

"W-wait, wait...you guys wanna let me in your relationship?"

Both Bakugou and (Y/n) stopped and stared at him. Kirishima blinked innocently.

"We're not dating." (Y/n) spoke.

"Yet." Bakugou closed his eyes and sighed through his nose.

"What?! I thought you were!" Kirishima exclaimed.

"I thought you and Bakugou were dating!" (Y/n) laughed.

"And I thought you two were a thing." Bakugou growled. "Anyways, Kiri, do you wanna date us or not? Like a polyamorous thing or some shit."

"Ye-yeah! I'd be honored!" Kirishima blushed. "I...I never thought this would happen...I'll be the manliest partner you two will ever have!"

"Alright don't get all emotional on us." Bakugou deadpanned.

"Aw Bakugou, leave him be. I'm getting a little emotional myself..." (Y/N) smiled sweetly up at Bakugou.

Bakugou blushed slightly and looked away. "Tch. Dumbass..."

Kirishima stepped closer to his new partners. "You...you guys are serious, right? It's not a dream, right?! (Y/n), pinch me!"

(Y/n) chuckled as they pinched Kiri. "It's not a dream."

"If it is a dream...I never wanna wake up..." Bakugou mumbled the last bit, still looking away.

"Huh? What was that?" (Y/n) looked up with Kiri.

"I said I...I never wanna wake up." Bakugou refused to look at his new partners.

Tears welled in Kiri's eyes, and he wiped them. "S-so, should we...should we plan a date? The three of us?"

(Y/n) grinned. "Yeah! Katsuki, what're you thinking?"

"Tch. Of course you'd choose the most superior planner." Bakugou gained his confident smirk back. "A dinner tonight. 8 pm. We all meet up at this noodle place tonight."

"Oh! Matsutake? That just opened! I've been wanting to go." Kirishima flashed his sharp teeth.

"Yeah." Bakugou nodded. "(Y/n)?"

"I'm game." (Y/n) grinned themselves.

"Good. I'll meet you both at the doors at 8pm sharp." Bakugou then kissed both Kirishima's and (Y/n)'s foreheads. "And don't be late, dumbasses!"

Then, he left his new partners dumbfounded. (Y/n) was the one to break the silence.

"S-sorry this was all so sudden, Kiri..."

"No no it's okay! I'm just as surprised as you are."

"Yeah, Katsuki sure has a way of surprising everyone..." (Y/n) covered their red face with their hands.

Kirishima chuckled. "Yeah, only Katsuki can make the first kisses then leave like nothing...anyway, you should probably head home so you can get ready for our date! Unless, you want me to dress you up in my clothes?"

(Y/n) laughed. "While very tempting, I'm not sure Katsu would like that very much. I'll see you there, Kiri."

(Y/n) then kissed Kirishima's cheek and left without another word. From outside, they could hear Kirishima losing his mind. It made them laugh.
