Kanae sat down in the office, admiring Sanemi from afar.

Sanemi, the math teacher, was always seen as scary and strict to to his students. Though, he was really nice to his brother Genya who was attending the school.

Some people saw his soft side and some haven't yet. And Kanae was one of the people who saw his soft side.

She sighs. "Oh my~ I have a lot of grading to get done!" She exclaims to herself, but Sanemi, the only one in the office right now, heard it.

He smiles at her as if she's his whole world. Because she is. Sanemi fell for her ever since the Biology teacher, Kanae, helped her with his wounds he got from a roberry.

He remembered how Kanae blushed at his abs, seeing how fit he was. It was flustering to her, since it's the first time she saw a guy shirtless. 'He must go to the gym often.' She thought and imagined it, Sanemi shirtless, sweat rolling down his body while he runs on a treadmill or lifts weights...

But while the nurse is gone, she has to focus on first aid! No time for day dreaming or any fantasies!

She gets a wet towel and wipes off the blood from his chest, gently sliding it afraid it'll hurt. "Kocho-san, that kinda tickles. You know you could just rub it normally instwad of slowly and gently?" Sanemi said, looking at her.

"Ah, I was afraid I might hurt you, but if it tickles then sorry! I'll try wiping off the blood normally~" Kanae said eye smiling.

As she wipes while humming, all the blood done, she gets the alchohol and a cotton, puts the alchohol into the cotton, and finally, applies it to Sanemi's wounds.

"My my, this'll leave a scar, Sanemi, are you okay with that?" Kanae asks the silver-haired boy, concerned.

"Yeah, it's easy to explain to my future wife anyways." He responds, looking at how Kanae gently applies the alchohol and looks up to her.

"I wonder who your future wife will be." Kanae smiles, wishing she would be the lucky girl.

But that was the moment Sanemi realized his feelings for the girl.

The silence was deafening for both of them as the only sound was their breathing, waiting for the nurse to arrive.

Finally, the door opens revealing the one and only nurse, Kocho Shinobu. "Ah, sis! Are you done treating Sanemi? Did you apply the alchohol and stuff?" Shinobu asked, and Kanae nods.

"Yep, you can put the bandages now. I didn't hurt you, did I Sanemi?"Kanae worriedly asks. He shook his head, 'She's such a kind girl.' He thought. 'She would definitely make a perfect wife.'

He smiles out of the blue, luckily, no one noticed. And Kanae looks at her watch. "Oh my, look at the time! I have a class in the next fifteen minutes, I gotta go, Shinobu, you take care of him, bye you two!" She rushes out, and Shinobu sits to where Kanae was sitted.

"So Sanemi, do you like my big sister?"

Sanemi thought about that question forever now. And now the urge to help Kanae with her paperwork was a sign of that.

'Damn it! I like her.' He thought as his legs were moving on his own, to Kanae's desk until he was just standing there like a breathing mannequin.

Kanae was too focused on her papers which gave Sanemi enough time to think about probably going back until, timing decided that they're destined for each other.

"Ah, Shinazugawa-san! How are you doing? What is it I can help you with?" She eye smiles at him, and Sanemi smiles. "I want to help you, actually. You seem to have a lot of paperwork and I've just done mine." He says, not really lying since he did technically finish his.

"Oh my! Thank you so much Sanemi! Come have a seat." Kanae grabs an office chair next to her desk that she shares with Rengoku and pats the chair, signalling him to sit down next to him.

She gives him a red ballpen and a paper needed to be graded.

"So first number is A. A for-"

"Aylabyu." Sanemi says, smirking but cringing at the joke he made.

Kanae stares at Sanemi wide-eyed. "Ara ara~ The office isn't for flirting, but I love you too, Sanemi." Kanae smiles at him, this time, now catching Sanemi off-guard.

"What!?"

Sanemi is just misunderstood tbh.
