Haruka was your teacher. She was a nice but also strict teacher. She’s also your class adviser and you and your classmates call her Ms. Kiritani.

One day, Haruka was on her way to the faculty when she suddenly heard a noise in the distance “Huh?” Haruka mutters with her eyebrow raised and she walks to the source

What Haruka saw was you getting bullied by Airi! When you saw her, you said: “Ms. Kiritani, Airi is harassing me!” Hearing that, Airi froze and made eye contact with Haruka

Haruka was shocked in what you told her and she looked at Airi angrily for what she did to you.
