"Blake… doing this in the classroom… isn't it kind of risky?"
The morning sun was bright and crisp.
Inside the empty classroom, a cute blue-haired girl clutched at her chest, lightly biting her soft pink lips. She looked at the boy in front of her, her pretty face flushed with embarrassment and nerves.
"What if someone walks in on us…?"
Sitting across from Yanami Anna, the black-haired boy had clear eyes, neat brows, and pale skin. Faced with her hesitation, his expression didn't change at all.
"Relax. My nickname is Sharpshooter. Ten seconds is more than enough for me to empty a magazine."
"B-but…"
Anna's gaze drifted nervously toward the hallway outside the window.
"What if a classmate happens to pass by and secretly takes a weird picture…"
"Forget sneaky photos. Even if someone walks in and watches, I won't be distracted."
Blake cut her off flatly. He tapped the desk and gave an unquestionable order.
"Come here. Then lie down."
"…"
Faced with his sudden firmness, Anna could only blush and obediently do as she was told, nervously lying face-down on the desk.
"P-please be gentle…"
"Don't worry. I've been gutting fish for thirty years. My hands are steadier than a lithography machine."
"You're only sixteen, okay?!"
"…"
Blake opened his bag and took out the necessary tool, then looked down at the girl lying on the desk.
Her delicate, doll-like face. Eyes as blue as the sky. Skin pale like it had been soaked in milk. Blue hair swaying softly in the morning breeze. And that slender waist…
Setting aside her sea-otter-level appetite, his childhood friend, Yanami Anna, really was a ridiculously cute girl.
Right now, she lay obediently on the desk, glancing at him timidly as she whispered,
"Blake, you really have to be gentle… if you're too rough, I might get hurt…"
"Stay still. Don't talk."
Holding an ear pick, Blake carefully guided it into her ear with perfect precision, his face expressionless the whole time.
"I'm just cleaning your ear. If you talked less, we'd already be done."
From kindergarten to high school, the two of them had always been in the same class. A textbook example of childhood friends.
Today they were on cleaning duty. Right after finishing, Anna had complained she was hungry and pulled out a box of cream puffs, immediately going into full-on binge mode.
Blake had been quietly reading when he suddenly heard her desperate cry.
"H-help—help! My ear is so itchy!"
"Clean it yourself."
"I can't! My hands are covered in cream—it'll get into my ear!"
"Then go wash your hands."
"It's unbearable, I can't even make it to the bathroom… if you don't help me, I'm going to roll around on the floor!"
"…"
Faced with her pitiful pleading, Blake had no choice but to help.
"…That should do it. How does it feel now?"
He let out a small breath and straightened up, asking for feedback.
"Hehe~ it feels great. Didn't hurt at all."
Anna quickly sat up, her cheeks slightly pink. She shyly tucked her hair behind her ear with her slender fingers.
"Blake, you're just as gentle as you were when we were kids."
He put the ear pick away and returned to his seat.
"Since you're fine now, go study. Don't come crying to me during exams."
"That's exactly your problem."
Anna puffed her cheeks unhappily, popped a cream puff into her mouth, and started chewing like a hamster with stuffed cheeks.
"When your childhood friend compliments you, you're supposed to be nicer—not just talk about grades all the time."
Blake didn't even look up.
"Don't talk while eating."
"Relax, I'm experienced. I won't choke."
"You'll spray crumbs everywhere."
"Whaaaat?! A cute girl would never do that!!!"
"…"
After finishing the rest of the cream puffs, Anna moved to the desk in front of him and sat down, looking at him expectantly.
"Blake, want to eat lunch together?"
"Hm?"
He raised an eyebrow.
Anna was one of the popular kids at school, always surrounded by friends. She usually ate with her girlfriends, so why invite him today?
"Because today is the day you meet that awful homewrecking cat…"
Anna muttered under her breath.
"What did you say?"
Blake tilted his head, confused.
"Nothing!"
She stood up, hands behind her back, her smile as bright as the sunlight outside.
"I made too much food this morning. I can't finish it all, so I thought I'd share some with you."
"Then it's settled."
She turned and walked toward the door.
"Let's not eat in the classroom. We'll go to the emergency stairwell… I'm heading to the bathroom first."
"Got it."
Blake agreed casually, not thinking much of it.
"Phew…"
Out in the hallway, Anna let out a quiet breath. She turned back to glance at the boy still studying inside the classroom. After staring for a few seconds, she reluctantly looked away.
"If I eat lunch with Blake today… then what's written in the diary won't happen, right?"
She hurried to the restroom, washed her hands, then slipped into an empty stall and quietly took out a notebook.
It was nothing special—palm-sized, pink cover, covered in cartoon stickers. A diary issued by the school back in elementary days.
As everyone knows, normal people don't keep diaries. And even fewer stick with it.
After graduating elementary school, Anna had tossed it into a drawer and forgotten about it for years.
Yet this morning, when she woke up, the diary had somehow appeared beside her pillow.
When she opened it, something even stranger happened.
The childish entries she'd written back then began to fade away, as if erased by an invisible hand. In their place, new lines slowly appeared…
It didn't take long for Anna to realize she might be dealing with something supernatural.
What bothered her even more was the title written inside.
[Loser's Diary — Yanami Anna]
"…That name is awful. It's clearly a Future Diary, okay?!"
The blue-haired girl puffed her cheeks and muttered unhappily.
A loser?
She was the childhood friend—the one who'd been by Blake's side since forever. How could she possibly lose?
[By the time you read this, you will already have lived your life alone…]
"I absolutely refuse that kind of ending!"
[XX Year XX Month XX Day][Weather: Sunny]
[You wake up and obtain a Loser's Diary that allows you to observe the future.]
[At first, you doubt it. But while passing a house, you witness a pair of cats knocking a flowerpot off a second-floor balcony—exactly matching the time and place written in the diary. You finally believe in its power.]
[Overjoyed, you celebrate by buying sweets while passing through a shopping street.]
[That night, you celebrate again with a volcano beef rice bowl.]
[A week later, you celebrate with mapo tofu.]
[Three years of high school pass. The boy you like, Blake, gets into the University of Tokyo. Your grades are poor, and you part ways.]
[After graduating from college, Blake marries Shiina Mahiru.]
[At their wedding, you sit alone in a corner wearing a hat. Your only companion is a dog.]
[While chatting with friends, you learn that the day you found this diary… was the day your childhood friend was taken from you.]
[That night, you drink yourself into a stupor.]
[The next day, you wake up hungover, board a plane, and leave the country—spending the rest of your life alone.]
