Teacher's Bet 18+

Chapter 5: ↳ osmosis⁵

BIOLOGY WAS ALWAYS a very...interesting class to say the least.

Miya Atsumu, a charming and charismatic man who had his unique methods of teaching his classes in a way that wouldn't normally fit in the normal category but the students loved him for it.

There was always something new when it came to the Biology teacher. No class was ever boring, activities and projects were a daily occurrence. His laboratory was always colourful with posters that littered nearly every inch of the bland walls. Equipment was neatly stacked and ready for use every lesson, pre-prepared.

There was a clear objective at the start of every class and Miya sensei would always make sure that it was reached. Students couldn't help but be comfortable in his lessons, enjoying whatever he has set for them. Even the most boring topics become the most fascinating.

"Osmosis" he barked good-naturedly, slapping the board with his hand as the class laughed. "A relatively easy concept that shouldn't be hard for ya. So we'll be doing the few different potato experiments on page 78 and 79 and then we'll go through the explanations afterwards."

He clapped once, making sure everyone's attention was on him as he grinned broadly. "Off ya go! And please handle the equipment with care." (Y/N) looked at Nishinoya, nudging his shoulder for him to snap out of his daydreaming. "You get these" she started, pointing at one side of the list. "And I'll get these ones."

All she received was a nod as the boy trudged over to the crowded counters, trying to peek through moving arms of their classmates since his short stature won't allow him to look over their shoulders. She quietly snickered to herself, moving in the opposite direction as the rest of the class was congregated over there as well.

They met up again after a few minutes, dropping the equipment on their table. She looked over, scanning the things only to notice something was missing. "Where's the measuring cylinder?"

Nishinoya slapped his hand against his forehead. "Shit I forgot that. Was too busy trying to wrestle Tanaka for the nicer scales." (Y/N) rolled her eyes with exasperation, shaking her head. "Of course you did."

"But hey" he grinned cheekily, lifting up the new scales into the air. "I won."

"And this is why you only have one brain cell". Putting her hands on her hips, the girl sighed with resignation. "I'll go and get it."

She walked over to the counter, checking through the trays but finding none. Looking around throughout the lab, every pair seemed to already have one. Miya sensei was writing down the instructions on the board, adding diagrams and drawings along with the notes.

Biting her lip, she decided to go to the storage room at the back, certain that she'll be able to find one there. The room in itself was filled to the brim with boxes, new arrivals and orders for more equipment as everything was organized and in place.

She spotted the glass beakers and cylinders at the back wall, neatly lined up. Walking over carefully, (Y/N) made sure to mind the boxes that slightly cluttered the path. The girl surveyed the large shelf stacked with gleaming crystal figures.

Humming to herself, she carefully browsed along until she found what she was looking for. Right there at the top, hung the measuring cylinders, immaculate and ready for use. Reaching upwards, she had to tip-toe as her fingers softly brushed against the rack.

The glass wobbled slightly but that didn't deter her determination. 'Just a little more' she thought, her tongue trapped beneath her teeth in concentration.

However a large hand beat her to it.

Eyes growing wide as a dark shadow fell over her figure, she jumped backwards and right against a solid chest. The spicy smell of cologne tickled her nose as the fumes trapped her on all sides. A heavy weight settled on her hip as she was pulled closer against the lean body.

"Be careful. Ya don't wanna go breaking my equipment" teased a smooth voice above her.

Looking upwards, she met the charming mocha eyes of Miya sensei who peered slyly down at her through his thick lashes. A carefree grin tugged at his lips, his arm outstretched to grip the shelf. "We wouldn't want that now would we?"

(Y/N) lost all train of thought as it flew out the window along with her dignity. The girl only managed to register that he still had his hand on her hip, the touch burning her through her clothes. "There weren't any more measuring cylinders in the trays so I-I uh, went to grab one from here" she stammered nervously, feeling like a specimen being intensely observed under a microscope.

His smile dropped into a smirk. "I coulda sworn I laid out the exact amount needed" he pondered to himself, 'hmming' under his breath, Miya sensei regarded her closely. "My bad" he chuckled, eyes crinkling as he cocked his head to the side.

Still entrapped against his body, she couldn't help but squirm slightly, feeling her breath run a little short. "Um, can I please get it? I still need to do the experiments."

The blonde man didn't budge at first, an unreadable emotion flitting across his face before he finally handed her the equipment she's been so desperately trying to get ahold of for the past five minutes. "Well here ya go" he chirped cheerfully, pushing it into her hand.

Miya sensei dropped his hand and moved to the side, letting (Y/N) pass as she hurriedly made her way out of the storage room, eager to leave the confines that started to dizzy her head with the man's overwhelming presence.

"Oh and (Y/N)" he called out after her, stopping the girl in her tracks as she looked back, feet shuffling.

The Biology teacher grinned widely, licking his lips as he casually leaned against the shelf. "Be careful when ya handle the water, don't wanna get yourself wet."

It felt like all breath was knocked out of her, especially with the way he was smiling, brown eyes gleaming - strongly reminding her of a sly fox watching it's prey.

She nodded once to show her understanding because the words wouldn't dare come out of her mouth as she scurried away, leaving the blonde man chuckling after her scrambling figure.

Not realizing Miya sensei just called her by her first name.
