Everyone be like "nooo fuck that teacher he's an asshole they're such a cute couple leave them alone". Lmao people think about it, what if this was a male teacher with a female student? Bet your ass you would call it a disgusting pedophile in less than a page. What's the difference this way around?
With Arase constantly messes around it's only matter of time before other people find out, lucky for them it was this teacher who did. If he was taking everything by face value, he would have called police immediately, because it doesn't matter if it was consented or not, pedophile is illegal. But instead, he actually gave them a chance to solve it quietly and saved Riko from possible trouble when someone else finding out. You think that's not already a consideration for both parties? Stop being hypocrite
