†žIn the end she did use it“ - Like we learned from the guy: I†˜m not going to stand up or lift my head until we see her using that rope in a sequel! And I†˜m going to shout so that people look at me!
Regarding what was *a-hem* 'discovered' that day (Rie loves taking the dominant position, Yoshiyuki loves to be dominated), In The End, There Can Be Only One Conclusion:
Well, I suppose prostration is one way to show how serious you are? And hey, nothing wrong with being tied up and blindfolded for your first time...And just like that, she discovered her S tendencies, and him his M tendencies.
Funny how things work out so well like that.
Calling her 'My Queen' and her actually going on to use the rope...Yeah, I think their relationship will be a long lasting one.
