I get what you mean lol, but in my highschool having relationships is a strict no no. I had a relationship back in highschool and when my classmates nominated me to represent the school in like a school contest, the teachers didn't allow it simply because I was in a relationship. You would be heavily gossiped in the faculty office if you had one.
My junior won the election and became President of the Student Council but she was given an ultimatum to either break up with her boyfriend and continue her position or not. Of course, she had no choice but to back off from the position as she valued her boyfriend.
Which was really really stupid, at least they didn't punish you if you had one but your opportunities really would be zero. I hated that school for that.
And reading this made me remember it again, so maybe it actually holds true for some highschools in Japan, not that I know really. It's such a stupid rule.
I’m sorry but this is just silly, this whole plot of opposing schools hating eachother is getting lazy and dragged out. It’s so dumb seeing the teacher act like this & I fear no backstory for the teacher can justify this it’s really dumb and makes me disinterested a bit on the story
