Blackmailing someone to have sex with you is generally not a nice thing to do! Legally, it's called "Coercion", and in some states it's a rape case (it should be one everywhere, but such is the world we live in). Coercion by itself is illegal too! IDK about the laws in Japan though, not that anyone in this manga's gonna use the legal system for anything!
Are you aware of what rape is? He *didn't* give him a choice. It wasn't consent, it wasn't a choice. He was blackmailed and therefore in that regard forced to sell his body. That's not consent and it's not in the least legal. That is rape.
If you're telling someone you will kill their family or in other ways hurt their loved ones if they don't pay with their body, is that not rape, if the person agrees? Someone threatening and you agreeing to avoid said threat from actually happening is not consent.
So Rogi is in fact still a rapist scumbag - and he knows.
I have a question concerning the prequel:
When Rogi forced Tatsuyuki to have sex with him. Technically, It wasn’t rape, it was more like Tatsuyuki selling his body(because he owed money to Rogi and didn’t want to be a burden for his dad). But then right after Nozomi took Tatsuyuki out of Rogi’s house, they were pretty much acting as if Tatsuyuki was kidnapped. Did i miss something?(i’m so confused)
