So Tsukasa is not the same as Yui because she discovered a new kink while Yui is able to let go of hers.... I think they’ll have a reversal of roles in their future.
@anim8tur They have a reversal of roles every time the doggy ties up her owner. To me, it's remarkable how easily each can go from submissive to dominant role, but it doesn't seem to cause them problems.
I don't know how bad this flag is, but I'm guessing that there's something Tsukasa thought she can deal with, maybe she has before, and this time she can't. And unfortunately, to Yui I think it will be a complete surprise.
