For teachers like Tengen, Rengoku, Sabito, Mitsuri, Kanae and Gyomei
They are all a good teacher. Too Good. That the students who didn't do there best feel guilty for having a high grade.
As for y/n, she is there favorite substitute teacher, this period, The principal asked y/n to be the temporary nurse in the clinic cause, Tamayo-san is out with her family which she rarely do.
Y/n could be only a substitute teacher for the meantime.
The other Teacher already left the school, only the meticulous math teacher, Shinazugawa-sensei is left still typing and trying what he can compute for his failing students grade.
Rengoku who just finished his work, Just asked the Clearly annoyed Sanemi. Each type is a equivalent full force swear and curse words to the student.
"Oh, so your going to work overtime today? Shinazugawa-kun"
" Isn't fucking obvious" typing hard to his Computer not paying attention to Rengoku.
"Well, I just finished mine or so I thought, but I didn't notice I have more, HaHaHa" He said, still have five paperwork to do and he can go home.
After 30 minutes he is finish and look at Sanemi who is cursing and muttering swear words.
"Any progression over there Shinazugawa-kun?" He asked while Sanemi just give him a irritated look.
"HA! What do you want?! I am not fucking done yet, okay, this shitheads is giving me a huge pain in the ass, I bet y/n already left home" He said but mutter the last part, He didn't eat lunch with you, since you both become busy.
He just click his tongue in annoyance, if it wasn't for his pathetic students, understand his lesson so simple, He wouldn't be working overtime, Rengoku just chuckle at him but left a black coffee for him.
"Good luck with it" he said and left, Only the sound of his tapping fingers could be hear.
Y/n was taking care a patient, which she wait for her to wake up, So she could go home. She even call a Cab for the weak student, when the student is finally going home.
"Time to go back and lock the clinic, Sanemi been so busy that we couldn't eat lunch together" She thought to herself, she was just passing by at the staff room, when a loud sound of typing could be hear from the staffroom.
Y/n is just curious who is the person, Working overtime.
