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.
Y/N chuckled, gently patting Kotaro’s head. “That’s right, Kotaro.”
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.
