Yay indeed! I could do a scene with Riku receiving the mail and reacting accordingly (going over to knock on Torikai's room while dressed in a presentable manner) or just have him be too bashful about it to even tell her that the law changed before the party starts. With week in between for random tease scenes to have occurred either could be quite plausible really, but I guess people already want to have the orgy party get started?
