Based on the viral, record-breaking, and award-winning Giphy sensation, this warm and heartfelt magical adventure stars a boy and his dog who learn that the happiness is the most beautiful thing of all.

Ai's self-portrait is wonderful, his grandfather says—it's just missing one little curve. What could that little curve be? Looks like it's time for Ai and his best friend, Aiko, to go on an adventure!

With Ai's magical scarf turned into a paper plane, the two friends fly around searching for curves. A fluffy cloud? A colorful rainbow? A moving melody? None seem quite right. It's only when Ai is back home thinking about the happy times he had along the way that he discovers the most beautiful curve there is.

In this fun and comfortingly sweet story, happiness is truly the most beautiful thing of all.
