Chapter 1: The Request
I was just beginning to thumb my way through a stack of test-prep books I’d snatched from the shelf when a girl turned into my aisle and approached me stiffly, a bit like a rusty robot, as if she was walking toward a firing squad.
“T-Tanaka-senpai? I… need to ask a favor.”
Yumi Sato’s face was roughly the same shade as the school’s blazer — someone had clearly dunked her in cranberry sauce and left her to marinate. She was staring at my indoor shoes as though they held the secrets of the universe. We were in the tomb-silent West Wing library of Toka Academy’s university-preparatory program, surrounded by the comforting must of ancient books and industrial lemon polish, while Tanimura-sensei glared daggers over her half-moon glasses like she was mentally drafting our expulsion letters in triplicate.
Yumi was the undisputed idol of the first-year cohort — the kind of girl who made people stop mid-sentence just to look at her. Long, silky black hair tied in a neat ponytail that swayed like a metronome when she walked. Big, expressive dark eyes framed by naturally long lashes. Creamy, flawless skin with the faintest dusting of hidden freckles across her nose that only showed up in certain lighting. And then there was her body — the type that turned our school’s summer uniform into something borderline scandalous. Generous, full breasts that strained the buttons of her blouse in the most innocent-yet-lethal way possible, a tiny waist that flared into softly curved hips, and legs that looked like they belonged on a magazine cover rather than in an academy hallway.
But what made her the class Madonna even more than her looks was her personality. Yumi was the girl who stayed after class to help the slower students with notes, who remembered everyone’s birthdays, who smiled at the shy kids in the back row like they were the most interesting people in the world. She was kind without being patronizing, helpful without making a show of it, and somehow managed to make even the most awkward person feel seen.
I kept my voice library-quiet. “What’s up, Sato-san?”
“You know my name?” Yumi Sato looked up in surprise.
“Heh. Everybody at Toka Academy knows who you are, Sato-san.”
She sucked in a breath. “Tanaka-senpai. I need you… to teach me how to kiss,” she whispered.
The sentence landed between us like a live grenade with the pin already pulled. Dust motes froze mid-twirl in the slanted sunlight. I blinked. Twice. Tanimura-sensei started aggressively Windexing her lenses, clearly prepping for the kill shot.
I cleared my throat. “Maybe we should take this conversation somewhere that doesn’t come with a live studio audience and immediate academic crucifixion?”
Yumi nodded so fast her ponytail nearly gave itself whiplash. “Third-floor storage closet.”
Five minutes later we were crammed into a glorified mop dungeon that smelled like bleach, old glue, and regret. Yumi had her back plastered to a shelf of moldering world atlases, hands locked together so tightly I was worried she’d cut off circulation to her own fingers.
“Why me?” I asked, honestly baffled. “You could quite literally have any guy in school lining up to give you kissing lessons.” Yumi was objectively lethal — a first-year goddess with a smile that could convince the dour, 500-year-old school principal to consider smiling back. She was so pretty she could snap her fingers and have half the baseball team writing love haikus.
She finally met my eyes. Big, dark, and so earnest it physically hurt a little. “Because you seem… safe, Tanaka-kun. You don’t date. You don’t gossip. You’re nice. I’ve been watching you since the beginning of the school-year. Every other guy in this school just stares at my chest instead of looking me in the eye. I’ve had six boys confess to me already who I swear didn’t know a thing about me other than my cup size!” She paused, then added with a tiny, self-deprecating smile, “You actually listen. You even remember little details. You’re kind. And — don’t hate me for saying this — I’ve heard through the grapevine that you kiss like someone who knows what they’re doing.”
I digested that. Kenji Tanaka: moderately high-performing yet otherwise completely unremarkable second-year student at Toka Academy’s university-preparatory program. And somehow I was being asked to become the human equivalent of training wheels to the most beautiful girl in school.
“…Okay,” I said slowly. “And what exactly are we working toward here?”
“Just kissing. For now.” She rushed the words, cheeks still flaming. “I’ve got a date next weekend. He’s a university guy. Older. Probably knows what he’s doing. I refuse to show up looking like some wide-eyed virgin who thinks tongue is a food group.”
The mental picture of her glossy lips on some smug third-year sociology major made something dark and greedy twist low in my stomach. I crushed it. This was charity work. Noble. Platonic. Right.
“Fine,” I said. “I’m in.”
Her whole face lit up like someone flipped every light switch in her head at once. “Thank you thank you thank you—”
I raised a finger. “Rules. Non-negotiable.”
She went still, attentive like a student ready for a pop quiz.
“Rule one: strictly educational. No catching feelings. Rule two: if a single whisper of this gets out, we’re both dead. So no blabbing. Rule three: you’re the boss. You start it, you stop it, you set the pace. Always.”
“Got it!” she chirped, practically vibrating with nervous energy. “I promise I won’t fall madly in love with you and write your name in my notebook with little hearts. Scout’s honor.”
I snorted. “You were never a Scout.”
“Details,” she waved a hand. “I can fake it.”
I stepped closer. The air turned syrup-thick. I could smell her — sweet cherry-blossom shampoo and the faintest nervous-citrus trace of her skin. “Let’s start easy. Just lean in.”
She did, rigid as a ruler. I brushed a silky strand of hair off her cheek; she shivered. I studied her: creamy skin, those secret freckles nobody else seemed to notice, the tiny tremble in her bottom lip.
“Relax,” I murmured, voice dropping lower than I meant it to. “It’s only me. I’m not going to grade you.”
Her lashes fluttered shut. I closed the gap and kissed her. Soft. Barely there. Her lips were velvet and a little chapped, pressed tight like she was afraid they’d betray her. I eased back.
“Better already,” I said gently. “Now loosen up. Don’t mash them together like you’re sealing an envelope. And maybe… kiss me back this time?”
She nodded, eyes still closed like she was praying. Second attempt: I leaned in again. This time her mouth softened, parted just enough for me to taste spearmint and heat. I nudged the kiss deeper — slow, controlled, showing her how to move, how to tease with the lightest flick of tongue. She caught on fast. Too fast.
Her hands slid up my chest, trembling, then looped around my neck. Fingers curled into my hair. A tiny, involuntary moan slipped out of her — barely audible, but it slammed into me like a freight train. I answered by sliding my palms under her blazer to the dip of her waist, thumbs brushing the warm skin just under the hem of her blouse. She arched into me without thinking, her ample breasts pressing soft and warm against my ribs.
The kiss turned heated without permission. Open mouths, slow slides of tongue, her sucking gently on mine like she’d been starving for it. Her hips rocked forward once — instinct, not decision — and the pressure of my body against hers made Yumi gasp into my mouth.
Danger. Sirens. I was supposed to be the responsible one.
I pulled back, breathing hard. Her eyes opened — pupils blown, lips wet and cherry-red, cheeks flushed.
“How… how’d I do?” she panted, still clinging to my shoulders.
“Obscenely well,” I rasped before I could censor myself. “You’re gonna ruin that university guy in about forty-five seconds. He won’t know what happened.”
She beamed, triumphant and dazed. Then the mention of him seemed to sober her. She smoothed her skirt with shaky hands. “Right. Um. Probably enough for today?”
“Yeah.” I forced another step back even though every nerve ending was screaming at me to pin her against the atlases and keep going. “Class. We should… class.”
She nodded, still dazed, gave me a tiny, crooked smile that was somehow dirtier than the entire make-out session. “Thank you, Tanaka-kun. Seriously. You’re a lifesaver.”
“Anytime, Sato-san.” I smirked despite myself. “Within the rules, obviously. I don’t want to hear you’ve been writing my name in my notebook with little hearts.”
Yumi’s eyes sparkled with sudden mischief. “Too late. I already have a whole page. It’s very artistic. Little doodles and everything.”
I laughed despite myself. “You’re dangerous, Sato-san.”
She slipped out first, ponytail bouncing like nothing had happened. I waited sixty full seconds, forehead pressed to the cool metal shelf, trying to convince my erection that trigonometry was actually very interesting.
I had no idea — none — that “just kissing” was my introduction to the most addictively dangerous class I’d ever taken.
