"Study instead of fangirling over us!!"
Five young teachers have been assigned to Hoshigaoka Academy High School. They have the looks, the personality, and their classes are interesting. Because of this, the students have taken to calling them the "Hoshigaku Five," treating them like idols throughout the school.
However, the teachers themselves... 🩵 "Mathematics is truly beautiful, isn't it?" 🤍 "That expression is a bit of a malapropism." 💚 "I just want to go home and play games." 💜 "Love is a precious thing." 💛 "I want to do an experiment..." ──None of them have any intention of becoming idols.
Photography, fan service, gifts, and social media posts are strictly forbidden.
And yet, every time there's a culture festival, sports day, or open classroom, a crowd gathers just to see them.
Furthermore, three female students have started shipping the teachers with each other, constantly filling "delusion notebooks" behind their backs. The teachers' popularity rankings are updated without their knowledge, and they spend every day denying it with all their might.

"TEACHERS ARE NOT IDOLS!!"
A poster with those words written on it is posted in the hallway of Hoshigaoka Academy again today.
The reason is simple.
Five young teachers are being treated as "idols" by the students without their consent.
Math Teacher: Tasuku Yasuda Japanese Teacher: Kyohei Mochizuki English Teacher: Jun Sakai Social Studies Teacher: Naruki Yagami Science Teacher: Shino Arisu
None of them have any intention of being popular.
Teach classes, supervise clubs, attend staff meetings, and if they can go home on time, that's a huge win.
...That's how it was supposed to be.
But in reality, high-pitched cheers erupt just from them arriving at school, crowds gather for open classrooms, they're expected to perform on stage at festivals, and even casual interactions between the teachers become hot topics.
"That's why we're saying, teachers are not idols."
Despite their desperate denials, the students' "fangirling" shows no signs of stopping today.
