Kyoto Animation: Hassou-hen  

Imaginations, Kyoto Animation CM: Hassou-hen, 京都アニメーションCM「発想編」, Idea

As you wait in the park for your friend to show up, your thoughts begin to drift away from reality. In your mind's eye, you see different parts of your environment change and morph into what you expect them to look like when your friend arrives. You become lost in these daydreams and visions as you immerse yourself in the fantasies that fill your mind.
