They are Lucky and Sky, playing with a kite.
It's kind of famous the affirmation that says that at some point, you and your friends went outside to play together for the last time and nobody knew it. But what if we keep playing, there is not a limit in our life to keep enjoying the pleasure of having fun for something is not serious and that is actually one of the most important things in the world.
