After Kotomi Izumi left the third music classroom—
Momoka Mito, after finishing a violin piece at a leisurely pace, didn't continue playing through the rest of the lunch break like she usually did. Instead, she packed up her violin, grabbed a bottle of water, and walked out. Rather than returning to Class 2-B, she turned and headed for the music teachers' office, also located on the fifth floor.
Knock knock knock.
Momoka gave the door a symbolic knock, then pushed it open without waiting and walked in with a cheerful grin.
"Miss Koishi, have you eaten lunch yet?"
She entered the music teachers' office, where Ami Koishi was the only one inside, and casually locked the door behind her.
It had been months, but Momoka had finally worked up the nerve to secretly order delivery—burgers and fried chicken. She was enjoying them with great relish when a sudden knock at the door startled her so much she nearly choked on the bite of burger she had just taken.
It couldn't be helped...
After all, the principal was Ami Koishi's father. Though he doted on her like a princess, he strictly forbade her from eating fast food like burgers and pizza. Every ti he caught her sneaking so, she got a thorough scolding. As a result, whenever she did indulge, she unconsciously ate faster, afraid of getting caught again.
Even though she was already a college graduate and a full-fledged teacher, she still had to worry about sneaking burgers behind her dad's back. Honestly, she should never have applied to a high school where her father was the principal!
Every ti Ami Koishi thought about this, she regretted it a little. Back when she was a student, even though her father spoiled her, he was always busy with work and often gone for weeks. She knew he was a principal at a high school sowhere in Chiba City, but not exactly which one.
After graduating college, she decided to apply to be a high school music teacher. With her credentials—and the general shortage of music teachers—her interviews at various schools had gone smoothly.
In the end, Ami Koishi chose to work at Sobu High School.
She hadn't told her father she was applying, thinking she was grown up now and should handle job hunting on her own.
But during the first all-school faculty eting after joining, Ami stared dumbfounded at the man sitting in the principal's seat—while her father also stared dumbfounded back at his daughter.
What is my dad doing here?!
What is my daughter doing here?!
To this day, Ami still found it hard to believe. Of all the high schools in Chiba City, she had picked Sobu High.
Because of that, she didn't dare order burgers for lunch even when she wanted to. If her dad wasn't busy, he might drop by the office to check if she was eating properly. And if he saw her eating fried food again, he'd definitely scold her just like when she was a kid.
So yes, Ami often regretted choosing Sobu High as her teaching post.
However...
After she t Momoka Mito, she often felt glad...
That she had ended up teaching at Sobu High.
"Ah! Momoka—cough cough—Mito-san, you scared to death! Don't you usually practice violin in the third music room during lunch?" Ami took a sip of Sprite before she could speak normally. That burger bite really had choked her.
"I missed you, so I ca to see you. And check if you're eating properly," Momoka said, stepping forward. Seeing that Miss Koishi was, once again, eating burgers, she let out a resigned sigh. "Sigh... Miss, how many tis do I have to tell you? Fried foods like burgers should be eaten in moderation."
"This is a grilled beef burger... not fried."
"You think I can't see that box of fried chicken on the side of your desk?" Momoka pointed straight at the box of drumsticks.
"Ugh—Why are you lecturing too, Mito-san? I'm the teacher, you're the student! I'm just craving it today, so I'm eating it!" Ami puffed out her cheeks in frustration. Despite being a teacher who worked hard to appear mature and reliable in front of students, she always acted like a spoiled kid in front of Momoka.
"Okay, okay, I get it~ Go ahead and eat. I won't scold you. I actually ca to ask about sothing—the key to the second music classroom. I want to borrow it for a while."
"Huh? Who are you lending it to?" Ami quickly asked. She was fine with letting Momoka manage the keys to the three music rooms, but that didn't an she could lend them out casually.
After all, these were school property. If anything happened, as a teacher, she'd be held responsible. She wouldn't mind taking responsibility herself, but what she really feared was if sothing went wrong and it affected Momoka—especially with just over a year until her college entrance exams.
"To Kotomi Izumi from Class 1-F."
"Huh? Izumi-san? Don't tell ... she thinks the music classroom is comfy and wants to use it for naps or sothing?"
Upon hearing the na Kotomi Izumi, Ami felt a bit hesitant. Kotomi often slept through her class, so the idea of her suddenly wanting the key to a music room made Ami suspicious.
"Don't worry, Miss Koishi. Izumi-san just told —she wants to use the music room to practice before the culture festival. She's amazing, you know? She's even planning to form a three-person band and perform on stage. Aren't you curious what her performance will be like?"
Hearing that, Ami couldn't hide her surprise.
"Izumi-san wants to form a band? And perform? I can't believe it... She's the type of student who sleeps in every music class... Well, okay. If that's the case, go ahead and lend it to her. You have the key to the second music classroom, right? Just give it to her directly."
Though she was still a little shocked—this was like a student who never did howork and always failed suddenly scoring perfect marks in every subject—Ami thought it over and ultimately nodded in agreent.
Since Momoka had co to her about it directly, Ami was willing to trust her judgnt.
"Hehe, I actually forgot the key."
"No wonder you ca to ..." Ami sighed helplessly, then took the key to the second music classroom from her drawer and handed it to Momoka—a silent sign of her approval.
"OK! Thanks, Miss Koishi~ I'll have Izumi-senpai co thank you herself later," Momoka said cheerfully as she took the key.
"So... you only ca to see today to borrow the key?" Ami asked, a hint of loneliness on her face.
Momoka shrugged and chuckled lightly. "Feeling lonely being alone in the office?"
And with that, Momoka stepped forward, wrapped her arms around Ami Koishi, and deeply kissed her on the lips.
Momoka had always believed she could never fall in love with anyone—that her heart belonged only to the violin. Until this year's music class, when she t Ami Koishi for the first ti.
And before they realized it, they had already beco lovers who had shared everything with one another.
"Mito-san... isn't the door still open...?"
"I locked it when I ca in. Ami, don't call Mito-san right now. Call Momoka, okay?"
"Okay..."
Though Momoka Mito and Ami Koishi had a teacher-student relationship, they were also lovers. And both knew that until Momoka graduated high school, their love had to remain completely hidden—without leaving a trace.
...
When Kotomi returned to Class 1-F and entered through the back door, she flashed an "OK" hand sign at Yukino Yukinoshita.
Yukino responded with a knowing smile.
gumi Kato, who happened to glance up from her phone at that mont, instantly felt sour. Her own girlfriend was sharing such perfect mutual understanding with another girl—like they were in on so secret she wasn't part of. Jealousy surged within her.
Pouting slightly in displeasure, gumi deliberately avoided looking at Kotomi when she sat down, pretending to ignore her.
Kotomi, still basking in the joy of successfully borrowing the key to the second music classroom, didn't notice gumi's mood at all. At that very mont, her phone finished updating Azur Lane.
The new event: "Rondo at Rainbow's End"!
Ever since she saw Elbe's new outfit "Ti to Show Off??", Kotomi had been dying to play the new version—she could hardly wait a second longer.
Now that the maintenance period was over and the update complete, she didn't bother checking any new event details. She went straight for the limited construction pool.
"Ugh... As much as I want to pull Elbe—her outfit is seriously so spicy—this event also has the new rainbow ship Ulrich von Hutten. And I didn't save up any Wisdom Cubes or resources in advance!"
Kotomi hesitated. With her current stock of Cubes, materials, and quick finish tools, she could only afford two ten-pulls. She still had over 5,000 gems, but those were strictly reserved for skins! She couldn't bear to spend them on resources.
She hovered over the "Start Construction" and "MAX" buttons, unsure.
Glancing to her left, then right, Kotomi noticed gumi was still focused on her phone. She blinked, then smiled slyly.
"gumi~"
She scooted over and, as usual, started acting cutesy.
Pout. gumi puffed up her cheeks, silently expressing her displeasure—a clear ssage: I'm not happy with you right now!
Kotomi wasn't dense or emotionally oblivious. She imdiately realized gumi was in a bad mood—and it seed to be jealousy?!
Even though she recognized gumi was upset due to jealousy, Kotomi still couldn't figure out why. She could understand gumi being in a bad mood—everyone had their monts. But getting jealous?
That was puzzling. She had just arrived in the classroom, and it hadn't even been five minutes since she walked in and sat down.
Kotomi ntally retraced her steps from entering the classroom until now. She couldn't think of anything she had done that would justify gumi feeling jealous.
Besides, the first person she looked at upon entering was gumi.
And gumi had been busy on her phone at the ti.
Kotomi's large, pink eyes were filled with confusion. She just couldn't understand what she had done to trigger gumi's jealousy.
Still, gumi was jealous and unhappy—and even if she didn't know the cause, Kotomi knew the fastest way to fix it...
She glanced around. The classroom was mostly empty. Those who remained were either glued to their phones, reading, or chatting quietly in groups. Everyone was absorbed in their own world and not paying attention to others.
Kotomi looked behind her. Mashiro Shiina had already finished lunch and was now napping face-down on her desk—clearly another late night spent drawing manga.
After surveying the area and confirming the coast was clear, Kotomi leaned over and quietly rested her head on gumi's lap.
Today, gumi was wearing mid-calf socks. Resting her head on gumi's lap, Kotomi was imdiately greeted by the soft, warm sensation of her thighs—so comforting that her eyelids began to droop, as if she might doze off right there.
Kotomi looked up at gumi with a playful glint in her eyes. "Jealous? What kind of jealousy? Who are you jealous of?"
The sudden lap pillow caught gumi off guard, and she didn't respond right away. anwhile, Kotomi's soft fingers slipped into gumi's hair, gently combing through it.
That light, gentle touch seed to carry a kind of magic, instantly soothing gumi's earlier frustration.
"You were exchanging looks with Yukino earlier..."
gumi felt like a childish girl in monts like this—whenever she let Kotomi stroke her hair, she stopped caring what Kotomi might think of her jealous outburst. She just wanted to say it all in one go.
She wasn't sure when this change had happened.
Since dating Kotomi, gumi—who used to be the one always taking the initiative—had gradually shifted. Now, she would occasionally act spoiled, like a little girl who hadn't grown up.
And she loved that feeling—loved acting spoiled with Kotomi. Once she started, she couldn't stop. She wanted to see how Kotomi would coax her.
Now that she finally understood why gumi was upset, Kotomi let out a helpless chuckle. She never expected that to be the reason!
That look she exchanged with Yukino wasn't flirting—it was just her silently signaling that she had secured the second music classroom.
She didn't expect gumi to catch that. Wait, wasn't she looking down at her phone at the ti? She must have been pretending to play on her phone while sneakily watching ...
Kotomi wasn't sure whether to tease gumi for always pretending to be absorbed in her phone while secretly watching her, or for revealing such a childish side sotis...
But either way, this version of gumi was truly adorable.
"Sotis you really do act like a kid, gumi... but then again, aren't we all just kids who haven't really grown up yet?"
Still resting her head on gumi's lap, Kotomi stroked her hair gently. Before she finished speaking, her hand subtly applied a bit of pressure—a silent cue for gumi to lower her head.
gumi understood imdiately and slowly leaned down.
When her face reached the right height...
Kotomi's cherry lips softly captured hers.
A rare mont—Kotomi took the initiative to kiss gumi.
She reached up with one hand to stroke gumi's neck, quietly but intensely seeking to take the lead in the kiss. But in the end, just like always, she failed.
As things deepened, gumi smoothly seized control.
While Kotomi lay on gumi's lap, gumi carefully leaned down, kissing her while grabbing her school uniform coat from the back of the chair and draping it over their heads—like they were simply taking a nap.
"You're even using the coat to cover us? Since when were you this cautious, gumi?"
"It's not just caution. Kotomi, don't you think kissing in a dim little space like this...—feels even more exciting?"
"You're so devious. Ugh, keep it down. Mashiro's still asleep. Don't wake her up," Kotomi whispered, her face red with embarrassnt.
"Okay~" gumi replied with a small smile. With that kiss, her jealousy had long since vanished.
And now...
She just wanted more kisses.
With the desk as cover and the coat casting shadows over their little space, they created a small private world where the two of them could quietly express their love.
