Math Teacher Sanemi x Biology teacher Kanae

Break and class

Tanjiro and his friends walk through the hall.
"Are you sure Shinazugawa-Sensei even like Kocho-sensei?"Tanjiro says.
"Who does Shinazugawa-sensei shout at?"Nezuko says.
"Everyone."Tanjiro says wondering where this conversation is going.
"And who doesn't he shout at."Nezuko adds to her previous sentence.
"He never shouts at Shinobu , kanao and aoi."Tanjiro says.
"That's because kocho-Sensei is the older sister of the 3 of them."Nezuko says.
"I mean...."Tanjiro starts his sentence but doesn't finish it.
They walk to the lunch hall.
Kanao talks with Aoi.
"I have to go do uniform check although Tomioka-Sensei will shout at me for my hair."Tomioka says.
Inosuke just eats in the background.
"What classes do you guys have after maths?"Tanjiro says.
"Biology."Kanao and Aoi say.
"Lucky I have Art well I guess Art isn't that bad."Tanjiro says.
"Uzui-Sensei is cool...until he threatens you with an F."Tanjiro says.
"Sad."Kanao says quietly in her usual monotone voice.
"Is that all you say to that."Aoi laughs.
An hour later it's time for next lesson.
Students listen to every single thing Kocho-Sensei says knowing the angry math teacher it next door.
"Can anyone tell me a cell or more of a plant?"Kocho-sensei says.
Many people put their hand up and Kanae picks someone .
"A nucleus, cell membrane, cytoplasm and mitochondria."The student says.
"Correct."Kanae says and then went back to teaching some stuff they already know but most of it they've only just learnt.And today everyone has learnt that the Welwitschia mirabilis is the toughest flower.
