Kai has flowers in his hands. He's very thankful towards the whole team for bringing him to where he is today. He's also very thankful for his loyal fans who love him for who he is and the way he dance. But he's especially thankful for a lovely noona who would stay up all hours in the night just to watch him dance away his thoughts.  

Sometimes everyone gets that feeling when they are alone. That there is no one by there side and that they have to face the world alone. Its a sad feeling. No one has to be alone. You don't have to stay, but I never wanted you to go. Baekhyun and Kai realize that when someone they love leaves their lifes forever that maybe, they aren't gone forever.
