Yuuri has exactly zero experience with (knowingly) seducing anybody. He's not even sure that's actually what he's doing. He's not even sure there's anything like actual desire there, or if he really intends this to go where things like this usually head. He does know, however, that this is good, unequivocally, that the cake is delicious and that he's starved for human contact and that Minami did in fact kiss him like it was something he wanted and the place he's in is dark and cold and he doesn't want to be there, and Minami is warm and bright and here.

He also knows, distantly, through that same pane of glass, that he's probably being an asshole by doing this, if he has no real intentions of ever doing something like it again. Remorse, he finds, seems to also sit behind the same glass wall. He can look, but not touch.

He can touch Minami.

So he does. He shifts closer, puts a hand on Minami's face to draw him back in once he's finished with the bite, but close enough to finishing it that he tastes like chocolate.
