Remember when

It was one test after test after test, and in all honestly, he was getting tired. Tadashi had many days where he’d feel tired after spending hours working on his project, only to take a break to run through the cafe and grab a snack or some coffee then head straight back into his compact-lab in the garage.

Taking out one of his ear buds, he could hear the soft rumble of the j-pop song he was listening too from the bud. He chuckled, turning the music down as he stared up at his creation. He waited a few moments before reaching up and pushing on the port, closing it softly. He stepped back, and cleared his throat.

“Ow.” He announced in the quiet room, holding his arms to his sides nervously.
Slowly, his creation came to life. A small red dot flashed along the bot’s screen, indicating it was filming their interaction. He smiled, looking up at the robot with hope. It blinked its eyes a few times before looking around the room and taking in the surroundings.

“Baymax?” Tadashi asked, stepping towards the bot.

Baymax then looked down at the boy, blinking his eyes again and scanning the smaller child. Tadashi was grinning, hope shined from his eyes as he waited for the other to speak.

“Hello, I am Baymax,” The robot started, “I am your personal---”

Sudden Baymax’s voice halted, causing Tadashi to stir a bit before an infuriating screeching sound erupted from the speakers in the machine. The boy staggered back, holding his ears and fumbling to move closer to his creation. Slamming his hand on the port, the blue chip revealed itself and he yanked it from it’s holder, the sound quickly shutting off and Baymax going back into his charging mode.

He sighed, holding the blue chip, then shaking his head and tossing it off into the garbage. He returned back to his desk, crossing off another thing from one of his papers before a knock at the door caught his attention. He paused a second, then he moved to the door, opening it.

“Aunt Cass, don’t worry--” Tadashi started before he realized who stood in front of him, “Ah- Hiro?”

Hiro smiled at the other, stuffing his hands into his pockets, “Yeah? You sound surprised that I’m here.”

Tadashi gulped, waving his hands, “O-Oh no it’s-- Well, you haven’t been here in a week or so--”

“Yeeeahh.. Sorry about that. Finals were making it hard to have free time, y'know?” Hiro chuckled, leaning forward a bit to peek over the boy’s head, “What was that noise..?”

Tadashi pushed Hiro back, coming into the hallway and shutting the door behind him, “It’s nothing! Just a project that I’m working on. It’s not anywhere near done yet..”

Hiro waited a moment, and Tadashi feared that he was going to push by him and into the room. Instead, the college man shrugged and nodded his head in understanding; really, the younger boy shouldn’t expect more from him than he actually does.

“Well..” Hiro sighed, turning on his heels, “Your aunt made some cookies on her break, and they’re waiting on the table..”

On heart beat, Tadashi flew past the older boy and towards the cafe from the narrow hallway. Hiro could hear the faintness of his shoes squeaky their way up the board steps and back into the house. A smile found it’s way to the man’s face as he peeked back over his shoulder, looking at the garage side door. He felt slightly hesitant, a turning in his stomach saying he shouldn’t peek-- But he never did follow his gut feeling, did he? No, instead he allowed his curiosity take control and lead him back down the hallway and to the shut door.

His hand hovered over the door knob for a second before wrapping his fingers securely around it. Turning the knob, he peeked into the garage. The ground was scattered with loose paper and other things of the sort. Hiro twisted his face up a little when he saw a part of an old peanut butter sandwich. Gross, Tadashi..

Speak of the devil, the small boy touched Hiro’s side, causing him to jump and throw himself back into the wall, slamming the door shut as he moved.

“That’s one way to peek in,” Tadashi offered, biting down into a cookie as he held one up to Hiro.

Hiro gulped, but smiled, taking the small treat and nibbling on the side, “You need to clean your workspace if you’re working on something. A clogged space equals a clogged head.”

Tadashi rolled his eyes, laughing, “Yeah, I’m sure Hiro--”

Hiro held his finger up, “Well, you were the one who told me.” He pointed at the younger boy, who now shown a soft pinking in his cheeks.

“Did I now..” Tadashi stuffed the rest of the snack into his mouth looking away from Hiro, “Anyway.. What exactly did you need from me?”

Hiro paused a second, holding a finger to his mouth to think before shrugging, “I just-- Kinda wanted to see you, I guess, like you said it’s been a week and all..” Now it was his turn to return the blush, rubbing the back of his neck sheepishly.

“Well, then lets go for a ride on your bike or something. Aunt Cass have been bothering me for the last few days to get out of the garage.” Tadashi wiped at his mouth, starting down the hallway towards the cafe again.

Hiro followed at the boy’s heels, “I need to fill up my bike, but I’ll be doing that tomorrow-- How about we just hang out at my house?”

Tadashi shrugged, taking his headphones out of his pocket as they reached the cafe, putting them on the counter, “Sure, that sounds fine. We can play video games or something..”

Nervously, Hiro put his hands into his pocket as Tadashi hopped off into the back room to tell his Aunt, “Yeah.. Video games.”

--

“Hiro you’re slipping. It’s mario kart and you are practically letting me win,” Tadashi hit the start on his control, pausing the level, “What’s gotten to you?”

Hiro shrugged his shoulder, leaning back into the couch, “I’m just not in my game today, I guess I’m too tired or something.”

Tadashi rolled his eyes, getting up from his place on the ground and sitting next to Hiro, “Then what do you want to do?”

Hiro stared at Tadashi for a moment who leaned closer in anticipation. He bite onto his bottom lip, looking away from the younger boy with a defeated sigh, “I’m sorry to break it to you, but.. I’m actually a boring person.”

Tadashi rolled his eyes, hitting Hiro in the chest and settling back away from the other, “That’s… Not a surprise.”

Hiro put a hand to his chest, making a small gasp, “You knew all along? Why didn’t you tell me?”

“Because..” Tadashi took in a deep breathe, “It wouldn’t have been as funny as it is now, you dope.”

Hiro flattened, sliding down in the couch with a pout as the boy giggled to himself, grinning at the elder, “Okay okay, very funny.”

Hiro propped himself up again, a small pop in his back allowing him to relax his nerves as he stood up and made his way to the kitchen. The other soon following after him with a small glide in his step as his smug expression continued to stay on his face.

“Tadaaaaassshiiii,” Hiro whines like he was five again, making a small hand motion to the younger boy, “It’s not that funny!”

“To me, it is.” Tadashi pointed out, crawling onto the counter and smiling at the other, “It’s with you, Hiro, everything's funny.”

Hiro rolled his eyes, opening the fridge and grabbing them both a soda. He set the cola next to Tadashi, a raise in his eyebrows, “So my life is like a sitcom to you, huh?”

The boy waited, taking a drink from his pop before answering, “Yeah, pretty much.” Tadashi then grinned, tipping his hat back as he laughed.

Hiro glared again, grabbing the hat from Tadashi’s head and putting it on his own, escaping from the younger one’s reach and towards his bedroom. A few sounds of struggling were heard behind the older boy before Tadashi was at Hiro’s back, standing on the tip of his toes, reaching for the hat.

The older one stepped into his room, grin wide on his face, “I may be a sitcom to you, but it’s not a short lived sitcom.”

“Oh, short jokes now, so original.” Tadashi responded, a border tone to his blushing face.

Hiro laughed, about to pick at the Tadashi’s height again when he was stopped short. Just as a blink of an eye, the other jumped, planting both feet on the door frame and allowing him to grow a few inches, waving his hands a few times towards the college boy’s head before his wrist was snatched by said man. Tadashi was quickly hauled even higher into the air, being held by his waist as Hiro lifted him up towards the ceiling.

Tadashi thrashed his legs, wiggling within the other’s hold, “H-hey--!!” He squawked, pawing at Hiro’s head, “Let me down! I hate heights, aaaugh!”

Hiro merely laughed at the boys struggles, only to retrieve more squeals of desperation as Hiro started to swing the poor child around. Tadashi pushed at Hiro’s hands in an attempt to escape to fatal hold.

“I-I said let me go-- Cmon, dad!” Tadashi quickly shut his mouth after the words slipped from his mouth, making Hiro freeze himself.

The two stayed in silence for a few moments before Hiro let Tadashi down back onto the ground slowly, the boy wobbling slightly as his feet touched the ground. He stepped back quickly, his face lost of all color as he stared down at his feet, the elder now becoming worried.

“H-hey.. Tadashi, it’s okay. Somethings slip, you shouldn’t--” Hiro began, but was only shut down when Tadashi raised his hand.

“I have to go.” Tadashi said plainly, quickly running out of the room without another word.

The soft slam of the Hiro’s front door only confirmed that the teenager was gone. He sighed, running his fingers through his hair as he felt a tightening in his chest. Aunt Cass said something about an accident with Tadashi’s parents, but never really said what it was.. He must really miss them.

--

Tadashi woke to his window opening, quickly grabbing his pillow and flipping on his lamp as he stood up and readied his so-called weapon. The only threat that treaded into the young boy’s room was .. Hiro. He was half in the window by now, holding a box to his side as one leg stretched into the room and the other on the roof that lay outside the window. He gulped, giving a small wave at the half-awake boy.

“..What are you doing here?” Tadashi asked, his voice hoarse and low.

Hiro blinked, almost not recognizing the boy’s voice before he finally pushed himself into the room, “I.. Brought you some donuts..?”

Tadashi stared for a moment, then smiled and dropped his pillow down, “Thanks..”

Hiro smiled, walking over to Tadashi’s bed and sitting himself on it, the younger one soon following after as the elder flipped open the box top open. He felt the small boy nearly jump into his lap as he grabbed the extra chocolate donut, stuffing it into his mouth and sighing happily.

“Mmm.. I’ve needed that.” Tadashi laughed softly, licking at his lips as he continued to chew at the bakery treat.

Hiro watched the other eat the donut happily, his eyes fixated on the younger boys lips as he finished off the gooey sugar. Tadashi’s tongue darted out, lapping at the extra frosting that smeared on his lips before looking up to the college boy.

He smirked, “What? Do I have chocolate on my nose again?”

Hiro’s face quickly heated up, looking away from the other and chuckling nervously, “Ah-- N-no I was just..” He went quiet for a moment, feeling Tadashi grab another sweet before he turned to the youth, “Looking-- Admiring, I guess.. Just making sure you’re really okay.”

Tadashi paused for a minute, carefully taking another bite of his food as he shrugged, crumbs falling onto his shirt, “Yeah, I just had a moment earlier. Sorry about that.”

“Hey, don’t be sorry, I mean--” Hiro coughed slightly, Tadashi having quickly stuffed his donut into the other boys mouth and sighing.

“Don’t.” Tadashi said quietly, “I’ve heard it before-- And I’m thankful you want to talk to me, but I’ve said it so many times that I’m numb to sharing my feelings on.. Them anymore. I just want to be--” He raised his hands for a moment, “..Okay..” Slowly, he lowered his hands.

Hiro remained silent, letting the words sink into the now heavier atmosphere. More than a few minutes passed before looking back at the boy, just as Tadashi did the same. They stared at each other, only making it awkwarder before the younger one stood, walking to the window.

“S-so.. Do you-- Have school tomorrow?” Tadashi asked as he shut the window, smiling wearingly at the man.

Hiro shook his head, “No, actually, we’re on break currently.. I was-- Hoping to spend this time with you. All my friends are visiting family, but you and Cass are as close as family can get..” He trailed off, looking down at the sweets and licking his lips nervously.

Tadashi’s smile stiffened slightly, quickly moving over to the other and taking Hiro’s face in his hands, “Are you okay? You’re getting mushy.. I’m worried that you may be an alien.”

Hiro laughed, leaning into the boy’s touch and grinning at him. “No, no, I just.. Care about you.” His face offered a soft shade of pink, “A-and Cass, of course.”

Tadashi’s hold tighten, his smile now growing. He nudged the box off Hiro’s lap with his knee, quickly wrapping his arms around Hiro’s neck and fixing himself on his lap, hiding his face in the other’s neck, “Hiro..” He whispered, his hold tightening.

Hiro’s hands automatically went to the bed, quickly grabbing at the sheets as his blush spread across his cheeks. He could feel the younger boy move his arms, pressing his small hands to Hiro’s chest and looking up at the larger boy.

He gulped, looking down at Tadashi and meeting the doe-eyes once again. The boy seemed to pause for a moment, averting his gaze then back up to the older boy.

“Can I..” Tadashi started, blinking a few times, “Can I kiss you..?”

Hiro froze, his arms twitching and stiffening slightly. He opened his mouth once, but closed it again, and to do it a few times before Tadashi sighed, taking the man’s face in his smaller hands and pulling his face to his own.

Their lips met loosely, and both seemed to just expect a small peck. But Hiro felt the heat rising into his abdomen, quickly moving his arms around the smaller body and pulling him into his chest. Tadashi gasped, balling his hands up into Hiro’s shirt as he squirmed, moving from the elder’s lap and getting onto the bed. Hiro, surprisingly, followed excitedly, getting on top of the smaller boy and continuing the feverous kissing.

Tadashi moaned softly against the other’s lips, his fingers tightening in the thin fabric of the other’s shirt and tugging on it, “H-Hiro..”

Hiro tangled his hair into the other’s hair, resting his elbows on either side of Tadashi’s head, pressing his crotch against the inner side of the boy’s thigh, rolling his hips against his constricting pants, “F-fuck.. Oh fuck-”

Tadashi gasped, letting his legs fall open wider before peeking up at the college student, “S-swearing now?”

Hiro paused for a second, giving Tadashi a small glare before taking the boy’s hips into his hands and slipping them down to his thighs, pinning them open and pressing his growing bulge against the other’s, earning a loud gasp from the other below him.

Tadashi flicked his hips up, getting more friction and a low growl from Hiro. He tugged roughly at the boy’s hair, pressing his lips to the younger one’s jaw, slowly dragging the kissed down till he reached his collar bone.

“H-Hiro--” Tadashi gasped, grabbing at the boy’s shoulders, “W-wait..”

Hiro automatically paused, pulling away from the small boy with wide eyes, “Did I hurt you? A-are you okay--”

“I’m fine, Hiro!” Tadashi insisted, a small laugh escaping his throat, “I’m just.. I’m worried. I like you, I just..”

“Hey,” Hiro spoke softly, leaning over Tadashi and taking his face into his hands, a smile spreading weakly across his face, “Don’t worry.. If you’re not ready, I won’t force you to do it.”

Tadashi went quiet, a smile settling on his face as he put his hand on top of Hiro’s, squeezing it softly, “... Thanks, Hiro.”

The college man nodded, leaning back as the younger boy sat up, slipping his legs under himself before he pressed his face into the other’s chest, wrapping his arms tightly around the other. Hiro froze, his arms shaking as he placed them around the other. He could feel his chest start to grow heavy, his thoughts starting to turn darker (what were you doing to him? how could you let it happen? just do it, you know you want to. He liked it, come on.) His arms tightened around the small Hamada boy, his hands clenching at the back of the loose shirt.

“Hiro?” Tadashi finally asked, breaking the silence as he looked up to Hiro.

Hiro’s eyes widened, looking down at the boy before his heart began to race, letting his hold slack, “..Y-yeah?”

Tadashi pressed his head into the crook of the other’s neck, closing his eyes, “Do you.. Like me?”
Hiro became silent, knowing he couldn’t just tell Tadashi no. Not anymore, after what he’s done, what he’s been doing. He’s been pressuring the boy ever since that night. The night he leaned over Tadashi in the kitchen and pressed their lips together-- He’s just leading him on, leading him into something that should have never started. But can he lie to Tadashi anymore?

Instead of answering, the elder nodded his head quickly, the small boy letting a squeal out as he wrapped his arms around Hiro’s neck and snuggled into his chest. Hiro’s arms fell to his sides as Tadashi hung onto him, a small hum to his voice.

“I like you too..” Tadashi said, tightening his arms.

Maybe, maybe he can just lie to Tadashi for a little longer.
