Eeeeeek, I just watched the subbed version of season 3 episode 80, and I thought there was some pretty heavy ConYuu going on!!!
So, after Yuuri overhears the maids gossiping, he and Conrad talk. Conrad tells Yuuri that he can walk away from being Maou, and Conrad will carry Yuuri away if Yuuri wishes.

here that literally, what Conrad says is "I shall carry you away barefoot if you wish." Yuuri laughs but Conrad is dead serious.
Fast forward to the after-party. There, Conrad tells Yuuri that things ended up OK even without Conrad carrying Yuuri away. Then Conrad says, "But it's a shame isn't it? I was serious you know."
Yuuri sweatdrops, and says, "Hey, speaking of that, where's Wolfram?"
To me, Conrad saying "but it's a shame isn't it..." sounds like a roundabout love confession. And Yuuri's sweatdrop, and being reminded of Wolfram by Conrad's words, seems like an acknowledgement of what Conrad just admitted.
I think I just fell in love with Conrad a bit more in this episode ^___^
