Akio hadn't tied up his hands so he should have been able to free himself prior to the aphrodisiac being applied. Is that the placebo effect in action?
No, it's the usual good ol' "horny effect" in action.
Yeah....not the most solid writing there. That guy's body was insane. He wouldn't have even had to touch the other guy hard to even get him away from him. Its just for the yaoi... Kind of took me out of it though. I guess we're supposed to believe he was under the placebo effect of thinking the guy had supernatural powers and was controlling him even before the aphrodisiac.
Literally Finding Nemo - yay!
