a/n — I NEED SEASON TWO OF SCHOOL BABYSITTERS ITS SO GOODDDDDD
The first semester of high school had barely begun when a new student transferred into the school from the United States.
y/n, full of warmth and energy, had barely stepped onto campus before she found herself drawn to the Babysitter’s Club. The moment she heard about it, she signed up without hesitation.
Her love for children was evident from the start. The little ones in the daycare adored her instantly, drawn to her gentle voice and kind smile.
Kotaro Kashima was the first to cling to her, silently reaching for her hand whenever she was near.
Taka Kamitani, on the other hand, was more outspoken, always demanding her attention and grinning whenever she praised him.
Kirin, the energetic girl, constantly wanted to play with her, while Takuma and Kazuma, the cutest twins, one always energetic and one always shy.
Even baby Midori, the youngest of them all, cooed happily whenever y/n held her.
Ryuuichi Kashima, the responsible and kind-hearted member of the club, welcomed her warmly. “It’s nice to have another person here to help out,” he said, smiling.
Usaida, the lazy caretaker, merely waved from his spot on the couch. “Great, another person to do my job for me,” he mumbled, grinning playfully.
y/n had already made herself at home in the Babysitter’s Club when she finally met the last member—Hayato Kamitani.
That afternoon, the door to the Babysitter’s Club room slid open, revealing a tall boy with short black hair, his baseball bag slung over his shoulder.
His posture was relaxed, his expression as uninterested as ever, but when his sharp eyes landed on the unfamiliar girl sitting among the children, they lingered for a second longer than usual.
The room was lively with the sounds of laughter and chatter. Y/N sat cross-legged on the floor, carefully stacking colorful wooden blocks with Kotaro, who watched with quiet fascination, his tiny hands reaching out to place another block. Just beside them, Takuma and Kazuma were racing toy cars across the floor, the younger twin mimicking his brother’s words with a slight delay.
“Kazuma, we’re going super fast!” Takuma declared, pushing his car forward dramatically.
“super fast…” Kazuma echoed hesitantly, gripping his car tightly as he followed Takuma’s lead.
Meanwhile, Kirin was bouncing excitedly beside y/n, tugging at her sleeve. “y/n, y/n! After this, let’s play house! You can be the mom, and I’ll be the big sister!”
Taka, not wanting to be left out, crossed his arms. “No way, y/n should be my partner in cops and robbers!”
“Cops and robbers!” Takuma echoed softly, nodding in agreement with his brother.
Midori, the youngest of the group, sat quietly in Y/N’s lap, happily chewing on a plush rabbit while observing the lively conversation around her.
y/n let out a soft laugh, glancing between the children. “One at a time, guys! We can play all the games, I promise.”
Just as she reassured them, the sound of the sliding door caught her attention. Looking up, she found herself staring at the boy who had just entered. His gaze met hers, and for a moment, the noise in the room seemed to fade.
“Oh, you’re that new transfer student,” Kamitani remarked, raising an eyebrow.
y/n blinked at him before offering a bright smile. “Yeah, that’s me! And you must be Kamitani, right? I’ve heard about you from your brother.”
At her words, Taka, who had been standing beside her, smirked. “She’s my favorite now, Nii-chan.”
Kamitani let out a sigh, stepping further into the room and ruffling his younger brother’s hair roughly. “Figures.”
Kotaro, who had been quietly observing, tugged on Y/N’s sleeve, his big eyes peering up at her. “Y/N,” he mumbled softly, as if confirming her name.
Kamitani merely huffed, his expression neutral. But as he watched Y/N interact so effortlessly with the kids—especially his little brother—he couldn’t help but feel something unfamiliar settle in his chest. He wasn’t sure what it was, but as he caught the genuine warmth in her smile, he had a feeling this new transfer student was going to be sticking around for a while.
Over the next few weeks, Y/N became a regular presence in the Babysitter’s Club, always doting on the children and making them laugh.
Kamitani, while not overly expressive, found himself watching her more than he realized. He liked how patient she was, even when they were causing chaos, and he respected how easily she could handle Taka’s stubbornness.
What he didn’t expect, however, was his brother’s boldness one particular afternoon.
The kids were playing while y/n, Ryuuichi, and Kamitani were seated on the floor, chatting about school. Taka, who had been quiet for some time, suddenly stood up and pointed at his older brother.
“Hey, y/n,” Taka announced loudly, “you should date my brother!”
The room went silent.
y/n’s eyes widened as she processed what he had just said. Ryuuichi choked on air, eyes darting between them, while Kamitani sat frozen, his usual uninterested mask cracking as his ears turned red.
Kamitani quickly smacked his younger brother on the head—not too hard, but enough to make Taka yelp. “Shut up, brat.”
Taka pouted, rubbing his head. “What? You like her, don’t you?”
Kamitani scowled. “That’s not—” He stopped himself, suddenly feeling self-conscious. y/n was still sitting beside him, and he could feel her gaze on him.
y/n, who had recovered from the initial shock, giggled. “That’s sweet of you, Taka.” She then looked at Kamitani, her expression amused. “I guess you’re popular even with your brother.”
“Tch. Annoying,” Kamitani muttered, but he didn’t deny anything.
From that day on, Ryuuichi and the others started paying closer attention, picking up on how Kamitani’s eyes lingered on y/n a little longer than usual, or how he always made sure she wasn’t overwhelmed with the kids.
They all knew he wasn’t the type to openly express feelings, but something was definitely there.
And then came Valentine’s Day.
That morning, Kamitani was met with a crowd of girls in front of his classroom.
“Hayato-kun! I made these chocolates for you!”
“Please accept mine, too!”
“I put a lot of effort into this—”
Kamitani barely glanced at them, hands stuffed in his pockets. “I don’t like chocolate,” he muttered flatly before walking past them, leaving the girls visibly deflated.
His classmates, however, weren’t about to let it go.
“Damn, Kamitani, you’re cold.”
“You just rejected all of them in one sentence.”
“Brutal.”
Kamitani ignored them. Valentine’s Day had never meant much to him anyway. That is, until a certain someone showed up.
During lunch, y/n entered his classroom, carrying a small bag in her hands. Kamitani blinked when she stopped in front of his desk, smiling at him.
“Happy Valentine’s,” she said, holding out the bag. “I made some chocolates for the kids too, but I wanted to give yours separately.”
Kamitani stared at the bag for a moment before taking it. “…Thanks.” Unlike earlier, he didn’t reject it. His classmates, who had witnessed the scene, immediately erupted into chaos.
“Wait, he accepted it?!”
“He just told all the other girls no, but he took hers?!”
“Kamiiii-taniii~”
Kamitani scowled at them. “Shut up.”
That afternoon, after school, he found himself standing outside the Babysitter’s Club room, gripping a small paper bag. He exhaled sharply before stepping inside.
As expected, y/n was there, playing with Midori while the others chattered. She turned when he entered, smiling as usual. “Hey, Kamitani—”
Before she could finish, he shoved the bag into her hands.
She blinked, looking down at the neatly wrapped chocolates and a small bouquet of flowers. “Oh… is this for me?”
Kamitani clicked his tongue, looking away. “Obviously.”
The room fell into silence. Then—
“NO WAY.”
The kids and Ryuuichi gawked, while even Usaida sat up in shock. Taka, who had been watching closely, grinned widely. “See! I told you he likes her!”
Kamitani groaned. “Taka, I swear—”
y/n giggled, shaking her head before stepping closer to Kamitani. She held the flowers carefully before leaning up and pressing a soft kiss to his cheek.
Kamitani’s entire face turned red.
The room exploded.
Ryuuichi was speechless, Usaida was laughing, and the kids were either screaming or giggling.
Kamitani, still processing what had just happened, groaned into his hands. “I hate all of you.”
y/n only smiled, hugging the flowers to her chest. “Thanks, Kamitani. I really like them.”
And just like that, Valentine’s Day became a little more special.
SYNOPSIS…The second he walked in the club room he couldn’t take his eyes off her. She was beautiful. Not to mention bubbly and kind, nothing like him. The more he visited the club the more he grew attached. The way she spoke and understood the children only grew his interest.

“YOU’RE REALLY PISSING ME OFF Y’KNOW THAT OIKAWA. ━━━” Iwaizumi’s eyebrows twitched as him and Oikawa walked the schools’s hallways needing to pick up Oikawa’s nephew and Iwaizumi’s younger brother from Aoba Johsai High’s babysitter club.
Not many knew this but the school has had a Babysitter Club for quite a while now, primarily to cater to the needs of the busy parents who work at the academy, Iwaizumi’s mother being one of them.
Exactly why he was given the chore to pick his younger brother up from the club room and head home after volleyball practice. Oikawa on the other hand drops his nephew off at the babysitter club whenever volleyball practice ends late.
“Yeah whatever, it’s not my fault really!!” Oikawa rolled his eyes trying to ignore the death stare that was being engraved at the back of his neck.
“Y/N-Chan didn’t have a problem with it so neither should you.” He whined as Iwaizumi raised his eyebrows when hearing a name he had not heard off before.
It didn’t take long before the two made it outside the club room that surprisingly didn’t have much noise coming out of it. Well considering, it was late so it did make sense that most of the children would’ve went home with their parents.
“Y/N???” Iwaizumi asked before Oikawa quickly opened the sliding door that revealed a colourful and childish room which was definitely made for children.
“Taka! It’s time to go.” Iwaizumi shouted in an aggressive tone of voice the second the door had slid open, causing everyone in the room to be taken aback.
Though what caught his curiosity was a shorter female who stood beside the door him and Oikawa had just entered by. She seemed to be wearing the signature Aoba Johsai High uniform. Though he swore he had never seen her before.
“Who are you?” Iwazumi asked before turning his eyes the Conner of the room there he saw Oikawa’s nephew, Takeru and his younger brother, Taka.
“I-I’m the new helper here, Y/N L/N. Third year.” She said sounding extremely nervous. His eyes widened when seeing the girl turn her body around to face him…
Getting a good look at her he came to realise one thing, her beauty was captivating. She had her hair up in ponytail. While she wore the dark brown dress pants, a cream-colored sweater vest, matched with dark red tie, a baby blue, long sleeve button-down shirt being worn under.
“Yahoo, Y/N-Chan. I didn’t know you started today. That’s odd how come I didn’t see you around.” Oikawa greeted with a smile and wave. Causing Iwaizumi to be slightly shocked and curious on how the two knew each other.
“Actually I’m starting tomorrow, I’m just helping out here a day earlier.” She smiled avoiding eye contact and fiddling with her fingers.
“This is Hajime Iwaizumi, same year.” Oikawa introduced before wrapping his arm around the shorter males shoulder and leaning forward.
“I heard there would be a transfer student in our class. Would that be you, then? Good to meet you then.” Iwaizumi said. Despite looking scary he seemed to be a decent guy.
“Th-The pleasure’s all mine…” Y/N continued to fiddle with her fingers. Iwaizumi noticed it seemed to be a small nervous habit she had developed.
“Sorry. My club kept me out late. Mom’s still grading papers so I came to get him instead.” He apologised before looking down to see his younger brother wrapping his tiny arms and clinging onto Y/N’S foot.
“Big bro! I’m not goin’ home yet!” Taka yelled out, rubbing his face on Y/N’s leg while his grip on her only tightened. Acting like he was glued onto the girl.
“I told you we’re going home.” Iwaizumi said sternly, while Oikawa and his nephew stood beside the two brothers used to their complicated relationship.
“No! No! No! I’m gonna play with Y/N some more.” Taka cried before running or more specifically waddling towards his older brother and punching his leg.
“No throwing tantrums!” Iwaizumi scolded before harshly hitting Taka on the head, causing the toddler to cry and throw a fit.
“Hey, You didn’t have to hit him..” Y/N fiddled with her fingers , a nervous smile on her lips after seeing the volleyball player’s scolding method.
“Words aren’t enough to convince him.” Iwaizumi stated, while ignoring Taka’s cry at the same time.
“Big bro, you meanie! Meanie! Meanie!” Taka shouted. Tears streaming rapidly down his cheeks.
“Hey L/N, Mines handled you should pay attention to your own.” Iwaizumi pointed towards the Conner of the room where a toddler , around Taka’s age sat silently holding a children’s story book.
“He looks lonely all by himself.” He stated. The toddler had short, light-colored hair and a sleepy look on his face. The exact opposite of Y/N who have a very sweet and gentle look on her face.
Although the two didn’t exactly look the same, like him and Taka who were somewhat identical. The two were definitely siblings.
“Right.” She nodded. Sweating at how Iwaizumi picked up his crying little brother by the shirt, trapping between his left arm despite his cries and disagreements.
“See you.” The two third years turned around waving a goodbye to the girl.
“Bye Iwaizumi-san, Oikawa-san.” She waved watching the figures of the two slightly disappear the further they walked out the door, before turning around and walking towards her younger brother.
Iwaizumi watched at how Oikawa happily listened to his nephew who was speaking of some type of video game that came out. Though, truthfully something had been going through his head.
“I didn’t know you two knew eachother?” Iwazumi muttered, catching the attention of the brown-haired setter. Who was slightly surprised about his sudden question.
“Who? Me and Y/N?” Oikawa asked. Seeing how Iwazumi stayed silent but had a stern look was more than enough to answer him.
“I met her once in the babysitter room, when she was taking care of Takeru. We had a small conversation and that’s it… Though I have heard a few things…” He answered, making Hajime’s eyebrows raise.
“Apparently both her parents didn’t make it out a plane-crash, so the chairwoman had put her and her younger brother under her care. That’s why she’s such a sudden transfer.” Oikawa continued shocked at how fast rumours can spread.
“Though she’s a total cutie. Definitely worth to get to know. She’ll fit right in so we don’t gotta worry about a thing.” Oikawa smiled stretching his arms, blushing. On the other hand Iwaizumi only sighed at how quick he was to change subjects.
“Damn Oikawa you Idiot-” He was cut off by a yell coming from behind them. Causing them to pause and see none other than the person they were just talking about.
“Iwaizumi!! Oikawa!! Please show me to the closet hospital with a pediatrics ward!” Y/N seemed to be out of breath as she held her younger brother who was covered by her school jacket. It seemed he had a concerningly high fever.
Oikawa turned to look at Iwaizumi, nodding at eachother. Oikawa turned to grab Taka of Iwaizumi hands. Deciding he’ll be the one to take care of the children while Hajime guides Y/N to the hospital.
“Sure. Just follow me.” Iwaizumi ran with Y/N following behind him. Thankfully it didn’t take a while before they reached a hospital.
He stayed outside while Y/N stayed in the paramedics room with Kotaro. Though secretly he did try listening in to their conversation.
“It’s probably just a fever caused by stress from a change in environment.” The doctor said, placing a hot towel on kotaros head.
“His sleeping now, but the fever should go down after a bit of rest. No need to worry.” He smiled moving his hand on top of Y/N’S head to reassure her.
Thankfully, it wasn’t something to be worried about. Though the stress and panic had seemed to get to the girls mind. Causing her to want to step outside for a breather.
She hoped to find Iwaizumi waiting outside, so she could thank him, but she couldn’t find him. Giving her the idea to think he went home.
She sat herself down outside on the staircase, not caring that it was cold and she was shivering. She felt tears start to fill the brim of her eyes. Until a sudden interruption caused her to snap out her thoughts.
A neck scarf was thrown onto her head, messing up her hair. She looked up to see Iwaizumi staring at her not failing to miss any detail about her gorgeous face.
“You’ll get a cold… so any news?” He asked, handing her a bottle of water before seating himself down on the steps right next to her.
The scarf fell onto her lap before she then picked it up and wrapped it around her neck. slightly flustered of his actions.
“It was just a normal fever, nothing out the ordinary.” She replied sounding much calmer than before. Though that didn’t stop her with fiddling around with her own fingers.
“I’m glad.” He said. The both of them continued to stare in front of them in a comfortable silence. Until Y/N tapped Iwaizumi on the shoulder.
“Thank you, Iwaizumi.” She whispered, as the two of them finally held eye contact, causing the volleyball player to smile.
Soon the entrance door opened behind them revealing kotaros cries and a nurse trying to calm him down.
“Thank goodness! Kotaro’s big sister! He started crying the moment he woke up, and he just wouldn’t stop.” The nurse explained as Y/N and Iwaizumi had lifted themselves from the steps.
Kotaro’s cries became softer, the instant he saw Y/N who reached out grabbing Kotaro out of the nurses grasps and hugging him.
“You’re free to take him home now..” The nurse told them not wanting to cause anymore problems for the two who she assumed to be a ‘couple.’
When walking out Iwaizumi was curious to see Y/N pause her footsteps to slowly unwrap the scarf that sat on her neck. He wasn’t aware that he gave her the impression that he wanted it back. Cause in reality he likes seeing it on her.
“Keep it..” He muttered, wrapping the scarf back on her before placing his hand back in his pocket. Y/N stood there flustered when seeing the Volleyball ace walk in front of her like nothing happened. Though in reality there was an unnoticeable tint of pink shown on his cheeks he did not want her to see
“Are you alright to go home by yourself? I would walk you home but I need to pick up my younger brother from Oikawa’s.” He asked turning behind him to face the gorgeous girl.
“I’ll be fine.” She smiled, her eyes glistening while looking down at Kotaro who was soundly asleep in her arms.
“See you tomorrow, right?” He asked, aware that she was starting Aoba Johsai High tomorrow but still wanted to make sure.
“I’ll be looking for you.” She smiled, watching Iwaizumi walk away. Y/N looking for him, He wouldn’t mind that. In fact he’d like that a lot…
