Maybe this drug is the drug the uke took at the party and that’s why he can’t remember anything about that night. But i don’t think that the crown prince is the one who gave him the drug. I think the duke is the culprit and tried to have sex with uke but uke escaped and had sex with the crown prince instead...

Well no it’s not developed enough and a bit fucked up.
