Future Diary Marriage Wars! ~The Reincarnated Yandere Bride and My Never-Ending Popular Phase School Rom-Com~
Amano Yukiteru just wanted an ordinary school life. But when a mysterious email starts predicting his day with terrifying accuracy—down to the stray cat and the sold-out melon bread—"ordinary" goes out the window. Then Gasai Yuno appears: beautiful, perfect, and utterly obsessed. She knows his blood type, his favorite foods, the mole above his eyebrow... and she's convinced they're destined to be married. As if that weren't enough, Yukiteru's childhood friend Mirai insists the future isn't set i
Future Diary Marriage Wars! ~The Reincarnated Yandere Bride and My Never-Ending Popular Phase School Rom-Com~ - The Young Lady's Declaration of War, the Classroom Is a Battleground! ~I'm the One Who's More Suitable for Him~
Morning light slipped in thin through the gap in the curtains. Amano Yukiteru stayed curled under the covers, groping for his phone by the pillow. His fingertips touched the cold screen.
He turned it on. One new email. From the same unknown address as always.
"Today's Yuno Check"
"...Here it comes again."
Every morning for the past week, same time. The fact that he'd already gotten used to it scared him a little.
One week since that day.
The night Gasai Yuno had barged into his house, organized his fridge, cooked dinner, and gone home. The next morning, his phone had received a "Persons of Interest List" packed with the names of his female classmates.
And then, on the way to school, Nonosaka Mao had suddenly declared war: "I'm the one who suits him."
The name that had been added to his phone then.
"Nonosaka Mao (Classmate)"
"Danger Level: High"
Written in red.
Yukiteru rolled onto his back and held the phone above his face. He opened today's email.
"7:50 — Waiting at Kagami Bridge on the school route."
"12:30 — Amano Yukiteru buys bread at the school store."
"16:00 — Nonosaka Mao makes contact in the classroom."
"Note: Nonosaka Mao is a person of interest. Danger Level: High."
"Whoa..."
His voice cracked.
Mao's name was in red again today. And the letters looked bigger than they had a week ago.
(Danger Level: High... but Mao hasn't even done anything.)
Yukiteru set the phone on his chest and stared at the ceiling.
April mornings in Kagamihara City were still cold. His shoulders, exposed outside the blanket, felt chilly, and he shivered without meaning to.
"Hey, Yukiteru! Breakfast's getting cold!"
His mother's voice from downstairs.
"Coming, coming! I'm up!"
Yukiteru shot upright. He flattened his bed-head hair with his palm. In the mirror, the small mole above his right eyebrow looked sharper than usual.
(Please let today go by without incident.)
He prayed silently and changed into his uniform.
At the kitchen table, chewing toast, Yukiteru checked his phone again.
"16:00 — Nonosaka Mao makes contact in the classroom."
(Contact... what's she planning to do?)
A week ago, that morning, Mao had said:
"I will declare it plainly: the only woman worthy of you is me."
He remembered her face then. Chest out, ice-blue eyes aimed straight at him.
(She was beautiful... no, wait!)
Yukiteru shook his head.
(The problem is Yuno. What does Yuno think of Mao?)
That persons-of-interest list. Yuno wasn't writing it. It generated itself. But if it reflected Yuno's feelings...
(Yuno sees Mao as an enemy.)
He washed down the last bite of toast with milk.
"Thanks for the food."
"Mm-hm. Have a good day. Don't forget anything."
"I know, I know."
He stepped out the front door. The April wind carried a single cherry blossom petal to his feet.
When he reached Kagami Bridge on the school route, a pink-haired girl was waiting.
Long straight hair down to her waist. A small ribbon tied at the side. A thin silver bracelet on her left wrist. When she spotted him, her face bloomed into a smile.
"Good morning, Yukiteru."
"G-good morning..."
Yuno trotted over and stopped right in front of him. A scent drifted toward him—detergent mixed with something sweet.
"You woke up at 7:03 today. Good boy."
"H-how do you know that..."
"Because I check on you every morning, Yukiteru."
Yuno tilted her head. Her big pink eyes curved into crescent moons.
(Checking again...)
Yukiteru managed a wry smile. A week ago this would have been pure terror. Now he was getting a little too used to it.
"Hey, Yukiteru. Are you free after school today?"
"Huh? After school?"
"Yeah. I was thinking we could walk home together."
Yuno gave his sleeve a little tug.
"...Is that a no?"
She looked up at him through her lashes. Her pink eyes wavered, anxious.
"I-it's not a no..."
(But today Mao's supposed to make contact...)
The words from that morning's email surfaced in his mind.
"16:00 — Nonosaka Mao makes contact in the classroom."
(Something might happen before then.)
"Hey, Yuno. I might end up meeting with Mao in the classroom today."
Yukiteru said it with resolve.
Yuno's smile froze—just for an instant.
"...Mao?"
"Y-yeah. Nonosaka Mao. You know, my classmate."
"I know her."
Yuno's voice dropped, just slightly.
"Nonosaka Mao. The rich girl. The proud one who always carries a schedule book around, right?"
"Y-yeah, that's her..."
"Yukiteru, are you close with Mao?"
Her smile hadn't broken. But her eyes weren't smiling.
"N-not close, exactly—I mean, I just talked to her once a week ago..."
"Hmm."
Still holding his sleeve, Yuno stared at him.
"It's okay. I'll protect you."
"Huh? From what?"
"From everything."
Yuno smiled brightly.
And for some reason, that smile scared him.
When he got to the classroom, more than half his classmates were already in their seats. Yukiteru sat down and set his phone on the desk.
(Please let nothing happen today.)
He prayed. But at lunch, it happened.
Lunch break. Yukiteru had bought bread at the school store and was heading back to the classroom.
"Oh my, Amano."
A voice from behind. He turned. Nonosaka Mao stood there.
Softly curled blonde hair. Half pulled up, with a large ribbon. Ice-blue eyes looking at him with pride. She held her usual expensive-looking schedule book against her chest.
"Well, hello there."
"M-Mao. Hello..."
Yukiteru returned the greeting automatically.
Mao covered her mouth with her hand and gave a little laugh.
"Not with Gasai today, I see."
"Uh, well, Yuno's eating her lunch in the classroom..."
"Hmm. How convenient."
Mao opened her schedule book.
"Amano. Might I have a bit of your time after school?"
"After school?"
"Yes. I have something important to discuss."
Her ice-blue eyes pierced straight through him.
(After school... that's the time from the prediction.)
"16:00 — Nonosaka Mao makes contact in the classroom."
(So this is the contact.)
"Um, what's the important thing..."
"That's a surprise for after school."
Mao spun around, her blonde hair swaying.
"Then, after school in the classroom. Farewell."
She walked away with elegant steps.
Yukiteru stood there clutching his bread for a while.
(After school... but I promised to walk home with Yuno...)
(What do I do?)
After school.
The bell rang, and students filed out of the classroom. Yukiteru had his head down on his desk.
(If she's coming, let her come. No—I wish she wouldn't.)
Two voices warred in his head.
"Yukiteru, let's go."
Yuno stood beside his desk, beaming.
"O-oh, yeah... but, can you wait a sec..."
"What's wrong? You look pale."
"Huh? Oh, no, I'm fine..."
Just then, the classroom door opened.
"Oh my, Amano. Sorry to keep you waiting."
It was Mao.
The students still in the classroom all turned at once. A ripple of murmurs moved through the air.
Mao walked to the center of the room, schedule book in hand. Then she stopped in front of Yukiteru.
"...Oh my. Gasai is here too."
Mao's ice-blue eyes caught Yuno.
"Well, hello. Nonosaka."
Yuno looked back at Mao, still smiling.
"Hello, Gasai."
Mao smiled back.
But the air between them froze instantly.
The students still in the room watched with bated breath. Yukiteru, caught between them, couldn't move.
"Amano. Today I'm going to say it plainly."
Mao stepped forward.
"I am the one who suits you."
"Whaaat?!"
Yukiteru's voice cracked.
From around the classroom came a chorus of "Oooh..."
Mao puffed out her chest and continued.
"Not like Gasai's absurd, pushy excuse for love—I will build a relationship with you far more gracefully, far more intelligently."
"W-wait, Mao, what are you saying—"
"Amano. You should think carefully about which woman is truly worthy of you."
Mao pressed in on him.
Then.
"...Hmm."
Yuno's voice rang through the classroom.
Quiet. Cold.
Her smile hadn't broken. But her eyes weren't smiling at all.
"What exactly is Mao to Yukiteru, I wonder?"
"W-what..."
Mao faltered for a moment.
"A classmate, right? Nothing more, nothing less. Am I wrong?"
Yuno tilted her head.
"I-I am the woman worthy of Amano. This isn't about being classmates or anything like that..."
"Hmm. So you're a classmate."
Yuno gently placed her hand on Yukiteru's arm.
"Hey, Yukiteru. What is Mao to you?"
"Uh, um... a classmate..."
"Right?"
Yuno smiled brightly.
"I'm Yukiteru's future bride. So I'm just a little bit more special than Mao, aren't I?"
"W-wait, future bride—"
Mao raised her voice.
"Well, how rude! Future bride, you say? That's nothing but something you decided on your own!"
"It's not my own decision. Yukiteru and I are bound by fate."
"Fate?! How vulgar! Pushy love at its absolute worst!"
"It's not pushy. I just love Yukiteru."
"Just love him?! Have you ever once considered Amano's feelings?!"
"I do. All the time. For Yukiteru to be happy, all he needs is me."
"W-what is with that confidence?! Know your place!"
"I do know my place. My place is right beside Yukiteru."
"...!!"
Mao's face went bright red.
The air in the classroom turned taut.
Yukiteru, caught between them, could only flail.
"U-um, both of you, please calm down..."
"Yukiteru, be quiet."
"Amano, you be quiet."
Their voices overlapped in perfect unison.
"Eeek!"
Yukiteru stumbled backward.
(Why am I the one getting yelled at?!)
The students watched from a safe distance. Some were even taking pictures with their phones.
"Man, what a bloodbath." "You okay, Amano?" "No way he survives that."
The voices drifted over.
(I'm not okay! Help me!)
Yukiteru screamed internally.
He didn't remember much after that.
Before he knew it, he was out of the classroom, walking near the school with Yuno and Mao on either side.
"How did it come to this..."
Yukiteru looked up at the sky.
An April evening. The sky was a blend of orange and pink.
"Yukiteru, you're hungry, right? Let's stop somewhere on the way home."
Yuno said it while walking beside him.
"Oh my, in that case, I know a wonderful café."
Mao cut in from the other side.
"Amano, do you know 'Millefeuille' in Kagamizaka Shopping Street? Their tea is exquisite."
"Millefeuille—that old established café?"
"Yes. It's also famous as a gathering spot for diary holders."
"Diary holders..."
Yukiteru swallowed hard.
Millefeuille, the long-established café in Kagamizaka Shopping Street. A place where students with future diaries often gathered. Yukiteru had never been.
"Yukiteru, I want to go too. To Millefeuille."
Yuno tugged at his sleeve.
"I was the one who suggested it first. You should hold back."
"No way. I'm going too. I want to be with Yukiteru."
"You really are shameless."
"Mao's the one who shouldn't be crashing someone else's date."
"Date?! This is not a date!"
"It is a date. My date with Yukiteru."
"I-it is not! Amano, this is not a date, is it?!"
Mao pressed in on Yukiteru, her face bright red.
"Uh, um... well..."
(Whatever I say is a landmine!)
"See, Amano is troubled!"
"Yukiteru isn't troubled. Right, Yukiteru?"
"Uh, yeah... not troubled..."
"Liar! Your face is twitching!"
"It's not twitching. Right, Yukiteru?"
"I-it's not twitching..."
"See! Your voice is shaking!"
"It's not shaking. Right, Yukiteru?"
"I-it's not shaking..."
Yukiteru was in complete chaos.
In the end, all three of them went into Café Millefeuille.
An old wooden café tucked deep in Kagamizaka Shopping Street. The sign read "Millefeuille" in a cute font. Inside, antique furniture and soft orange lighting gave it a calm, cozy atmosphere.
"Welcome."
A female clerk greeted them warmly.
The three sat at a window table. Yukiteru in the middle, Yuno and Mao facing each other across from him.
"I'll have Darjeeling."
Mao said it while looking at the menu.
"I'll have a cream soda."
Yuno said it, closing her menu.
"...Cream soda?"
Mao furrowed her brow.
"Cream soda? At a tea shop? How childish."
"So what? I like cream soda."
"And you, Amano?"
Mao turned the menu
