I'm sad for Dae. He loves Kitty so much from beginning to end, and though that love was tested and measured by circumstances, he remains loyal to what he feels for her. In the end, he even lost his scholarship, and romantically it seems that Kitty is the only one that brings hope and joy to his life but still, he loses her. He is even about to fight and accept her for whoever she is. But it ended like he letting her go to be happy even without him... So I'm really hoping that if there's a season 2, Dae And Kitty will end up together.
