I also wanted Ren to tell the truth but I highly doubt Kyoko will ever know the truth about Ren and Kuon/Corn. For one thing, it is part of Kyoko's charm to believe in fairies and being exposed to the truth would in a way crush her spirit. Another reason is that Kyoko just realized her feelings for Ren and if Ren were to tell her the truth, Kyoko would be incredibly traumatized at being lied to and who knows what will happen to her then. Anyways, I found this chapter to be absolutely charming. All those adorable expressions made me kyun to death hahaha (>~<)
