Chapter 15

IT'S YOUR BIRTHDAY TODAY?! IS THAT WHY YOUR PHONE HAS BEEN GOING OFF LIKE CRAZY?!"

My realization had Shinsou sitting up, staring at us with a strange expression on his face.

"Why didn't you tell us that today was your birthday, Bakugo?"

Ooohhhh, snap. Shinsou used the calm collected voice with THE tone. Bakugo is in trroouubblleee.

He glanced between us, an almost shy look on his face. "I mean, it's not like it's a huge fucking deal. It's just a birthday. Besides, after everything that just happened, I kind of wanted to just… hang out with it just being us."

His face was bright red but Shinsou wasn't budging, he seemed almost angry.

"Bakugo. How old are you today?" When the silence stretches on, I cuddle back into my blanket, not sure where this was going.

"Is today your sixteenth birthday?" Shinsou asks, prodding the blond's bulky shoulder forcefully.

Sitting up, I stare between the two, knowing whatever the answer is will probably set Shinsou off. He nods his head slightly before trying to blow it off but the other was having none of it.

"Did you ever stop to think that your birthday would be important to us?" He scratched the back of his head and gave us a sheepish look shrugging his shoulders.

"How the fuck am I supposed to know that you're a sap about birthdays?"

Snorting, I pulled them both in for a hug, diffusing the tension. "It's all good. Let's celebrate this coming weekend."

They both agreed and we all curled up together, grabbing controllers and starting a heated game of Mario Kart. Mitsuki called again and we forced Bakugo to answer, literally stealing his phone and putting it on speaker.

"Hey, you brat! Why the hell aren't you taking my phone calls?" Her hollering was so loud that I quickly turned the call volume down on his phone.

"Listen, old hag! I told you I didn't want to do anything for my fucking birthday. Can you just drop it?"

"Katsuki you will get your ass down to this house tomorrow for a nice fucking lunch and you will invite those lovely soulmates of yours or so help me, I will come down to your dorm and drag you home myself."

The menace in her voice had me snuggling into Shinsou's chest but all Bakugo did was scoff and half-heartedly agree, burying his head in my stomach once the call was over.

"Are you fucking happy now, Shinsou? We'll all have to deal with that hag bitching at us for a couple of hours."

Shinsou hummed and ran his fingers through my hair and then flicked Bakugo's ear.

"Yes, I am happy now. Ren was right when she said you were the one here who has a biological family that cares about you and you shouldn't take that for granted."

A cramp shot through my abdomen and I curled into Bakugo's frame, basically wrapping around his face while letting out a groan. He wrapped his arms around me tighter and I felt his hands creep under my shirt, gently rubbing my back.

"Mmmm, your hands are warm. Keep doing that," I mumbled not caring how it sounded. His hands heated up a little more as he continued rubbing my lower back and it honestly felt like heaven.

I woke up after what felt like a short while later to realize that I was firmly tucked in bed between my two soulmates. A bare chest was inches from my nose and my back was plastered against an equally impressive physique.

Light was just starting to peek out from behind the curtains and my bladder was letting me know just how full it was. Gently trying to wiggle my way out of their embraces was made impossible when they both tightened their arms around me and snuggled in closer.

Huffing in annoyance, I tried to abruptly sit up but literally could not break free from their hold.

"Um, guys. If you don't let me go in like the next ten seconds, I'm gonna wet the bed." There was a small pause before they both released me, touch lingering on my skin as I scooted to the ladder.

When I climbed back up, they immediately held their arms open and I crawled back into the warmth, using them to chase away the chill from the room.

"You guys have absolutely no shame in your cuddle game." Shinsou snorted into the back of my neck and Bakugo just snuggled closer, face buried under my chin.

"No shame, shorty. You're warm as fuck and squishy, too." He grabbed my thigh and hiked it over his legs, squeezing it to make a point.

I squeaked and tried to pull away but there was literally nowhere for me to go seeing as I was already firmly pressed against Shinsou. Burying my hands in his hair, I pulled his head back and made him look me in the eyes but I regretted it instantly when I saw his adorable sleepy face.

"Bakugo Katsuki, you better stop teasing me."

"Alright," he mumbled before lunging forward and sealing our lips together.

His kiss was exactly like his personality, intense and aggressive. Our lips molded together and he darted his tongue out to have a taste, hand tangling in my hair to tilt my head more. I gasped at the unexpected heat and he bit my lip, not giving me a moment to breathe. When he finally pulled away, he was just as flushed as I was and panting like he'd just ran a race.

"That was hot," was said over my head and I looked over to see Shinsou wide awake, eyes locked on the two of us. I turned bright red and squeaked when he bent down and kissed my cheek before climbing out of bed to use the restroom.

The two of us followed his example and started getting ready for the day, all three of us going our separate ways to get dressed. Somehow, I managed to be the first one ready so I sat down and busted out my math homework, hoping to get a few sections ahead. Shinsou joined me and grabbed some paper, working alongside me quietly.

"Hey, can you help me with this? I don't understand the dynamics that they're talking about in this problem." I leaned over and looked at the problem he was on.

"Okay, you have to set up the proportions first and then cross multiply to convert the numbers to the measurements they want. Then you solve the problem by putting it in algebraic form." He nodded his head and started writing, not even glancing up at me.

"Hey, um, Shinsou," he looked up, pencil between his teeth as he thought.

"Are you alright with what happened this morning? I mean… I know we're taking it slow and what not…" He leaned back on his hands and gave me a slow once over, his gaze literally feeling like hands on my body.

"Are you okay with it? That's what matters to me."

I blushed and nodded, brushing my hair behind my ear. "Yeah, I'm okay with it. I just didn't want you to feel left out."

He snorted and pulled me forward by the front of my shirt, nose mere centimeters from his.

"I don't need to swoop in on someone else's moment. We'll have our own and it'll be right for the both of us. I'm not riding on anyone's coattail."

With that, he released me and went back to his homework, leaving me to gape at him in astonishment.

I think I'm just starting to see their personalities truly come out and I'm getting to see them discover themselves.

Bakugo barged in and gave me a strange look, joining us at the table.

"Did you fucking break her?" I snapped my mouth shut at Bakugo's rude question, sticking my tongue out at him.

"If you want to go again, squish, all you had to do was say so." I smacked my head on the table and the boys laughed, enjoying the power they had over me far too much.

"Just you jerks wait. The ball will be in my court and I will leave you flat on your backsides." Standing up, I told them I would run downstairs to grab us all food, asking them what they wanted. I ran downstairs, deciding to take the stairs to get a little cardio, loving the way my lungs didn't scream after the training I've been doing.

Oh, yeah! I'm gonna surprise everyone with my growth.

Ochako and Midoriya were in the kitchen, preparing a light breakfast and talking quietly. They both gave me bright smiles when I walked in, obviously surprised I was by myself.

"Hey! What are you two up to today?" Pulling out three containers, I quickly popped them in the microwave and hopped onto the counter.

"I was just asking Ochako if she wanted to go to the gym with me. Would you like to join us?" Ochako sent me a pleading look over his shoulder and it took everything I had to hide my laughter.

"Oh, no. I wouldn't want to intrude. Plus, we have to go to the Bakugo's house today. Mitsuki wants to celebrate Bakugo's birthday."

Midoriya instantly started rattling on about how he hadn't gotten him a gift yet and I really couldn't hold my laughter in then.

"Look, broccoli. Don't get him anything. He needs to earn your friendship back. You're a good guy and even he has admitted it… not in that many words of course. Just give him some time and give him some space. He needs time to work out his own issues."

The green haired boy gave me an incredulous look before bursting into tears.

"I'm s-so glad that Ka-Kacchan has someone like you in his life, Ren. Thanks for taking care of him."

Patting him on his head, I grabbed the three packages of food and headed back upstairs, opting for the elevator this time. I skipped out and smiled at Mina as she walked in after me, looking like she had spent the entire night awake.

"Girl, you need some sleep!" I hollered at the closing doors and she flipped me off.

Walking into the room, I found Bakugo trying to tell Shinsou that he should change. I looked down at my burgundy shirt and high-waisted shorts, wondering if I was too dressed down, as well.

As I was staring down at my outfit, I completely missed the look the boys shared. "Ren, you look cute. Bakugo's just being an ass because he's nervous."

"Oi! I'm not fucking nervous!" The blond yelled while shoving him over.

"Alright, break it up you two. Save it for our sparring sessions. And speaking of working out, I saw Ochako and Midoriya going to the gym together."

Bakugo didn't immediately blow up at the mention of his… rival… nemesis? However, he did turn very still, the wheels clearly turning in his head. Shinsou reached over and tapped his temple, garnering his attention.

"Whatever you're thinking, stop it. Just because he is working out on a day that we're not doesn't mean he'll surpass you."

He shoved the offending appendage away and glared. "I fucking know that, zombie. Just drop it."

I put the food down and sat between them, deciding to be the peacekeeper. We ate in silence and did homework at the same time, only speaking to ask one another for help seeing as we were basically two chapters ahead of the class.

All too soon it was time to head out and I felt butterflies erupt in my chest. The first time I had met Mitsuki she was very brash and her attitude seemed to only make Bakugo's worse.

Bakugo wrapped an arm around my shoulders and Shinsou claimed my waist, both seeming to be as nervous as I was. When we arrived, Bakugo paused before opening the door, giving us both a strange look.

"Oi, hag! We're here." A whirl of blonde came rushing through the hallway and smacked him on the back of the head.

I cringed into Shinsou's chest but other than that, I just watched the two yell at each other until Mitsuki turned to us.

"It that any way to treat your mother?! Hello, Ren. Shinsou. Why don't you both come in. I have tea ready in the living room."

We settled into the modern couch and watched as she poured us tea. "Katsuki, go get the cheese plate that's in the fridge."

He stood up without a word and disappeared, sparing us a backwards glance. "I'm so glad you both could join us today. I am sure that brat didn't tell you it was his birthday; he never wants to make a big deal of it. You'll both call me Mitsuki and my husband Masaru. It would be very confusing if you called all of us Bakugo!"

She giggled while she poured our tea with practiced hands.

"Yeah, we only found out about it because Ren here questioned him about the phone calls." Shinsou muttered, giving thanks for the tea.

"Ugh, that boy can be a menace when he wants to be. But I can already tell that having his soulmates has helped him grow. He calmed down so much quicker than he normally would!" Masaru walked in with Bakugo at his side, having a quiet conversation with one another.

"Alright, you three finish up the tea and then head up to Katsuki's room. We'll finish making lunch and then we have something fun planned!"

She reached over and ruffled Bakugo's hair, giving him an affectionate smile when he just rolled his eyes and sat the cheese down. We drank and ate in silence, listening to the domestic chatter just one room over.

"So… your mom is only like that with you?" I questioned, stuffing copious amounts of cheese in my mouth.

"Slow the fuck down! No need to choke yourself. Yeah, our personalities just clash and it's the only way we know to communicate. You know it's fucking serious when neither of us are being dicks to the other."

He emptied his cup and gave us a pointed look. We both downed our tea and followed him upstairs to his room.
