nope. Its rape 100% if he was drunk and didn't want it.
I'm just saying people who are drunk express themselves in different ways how do u know he didn't want it...there people who are drunk and they're personality changes maybe he was more honest that maybe he did something I'm not saying it's ok to rape but we don't what happen yet if he later fall in love with the prince and he's the baby father seeing as raped would be pretty weird..
although if they were both drunk that's be a double whammy lol. But we dont know yet.(〜￣△￣)〜
I don't think he was rape tho...I mean he was drunk if it's the prince who fuck him maybe there's a chance it was consentual I'm just saying they used to be friends and all
